PHP – Check if a number is Even, Odd, or multiple of another

While coding PHP applications, there are times when we need to check if a number is even, odd, or multiple of another.

Here are a few methods to do the same.

Method 1:

$number = 3;
if($number & 1){
    echo 'Odd number!';
}else{
    echo 'Even number!';
}

Method 2:

$number = 3;
if($number % 2){
    echo 'Odd number!';
}else{
    echo 'Even number!';
}

Method 3:

$number = 3;
echo ($number % 2 ? 'Even' : 'Odd');

Method 4:

Check if the number is multiple of another. This can be used to float DIV elements and remove margin from the last ones.

for ($i=1; $i <= 10; $i++) {
	if($i % 2){
		echo $i.' is not multiple of 2';
	}else{
		echo $i.' is multiple of 2';
	}
	echo '<br />'; // Adds a line break.
}

If you know of another method, do share these in the comments.

How to make Blurry Text with CSS

Its pretty easy to make some blurry text with CSS. We can do it by just making the text color transparent and adding some text shadow. Here’s the code for the same:

Blurry Text with CSS

To do it on the normal text we can create a class and use SPAN tag to make the text blurry.

Example: This text will be blurry!

HTML Code

<span >This text will be blurry!</span>

CSS Code

.blur{
    color: transparent;
    text-shadow: 0 0 3px rgba( 0, 0, 0, 0.5);
}

We can make the links blurry on hover by adding the blurry styles on a: hover pseudo-class.

<a href="" title="">This link text will be blurry on hover.</a>
a.blurry-links{
    color:red;
}
a.blurry-links:hover{
    color: transparent;
    text-shadow: 0 0 3px rgba( 0, 0, 0, 0.5);
}

You can always change the RGB values and the opacity for the text-shadow property and have the blurry text in a different colors.

An easy way to create Tabbed Content with jQuery & CSS

Tabbed content is a great way to handle a lot of information on a page without loosing usability and it provides a great user experience as well. Here’s a real easy way to create tabbed content with jQuery and CSS.

Let’s create tabbed content with jQuery and CSS

Step 1: Include the jQuery library

<script src=//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js></script>

I’ve used the latest version of the Google-hosted jQuery library, however, you can always download the script and host it on your server.

 Step 2: Write some HTML code

<div >
    <ul >
      <li data-tab="tab-1">Tab One</li>
      <li data-tab="tab-2">Tab Two</li>
      <li data-tab="tab-3">Tab Three</li>
      <li data-tab="tab-4">Tab Four</li>
    </ul>
    <div id="tab-1" >
      Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
    </div>
    <div id="tab-2" >
      Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
    </div>
    <div id="tab-3" >
      Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.
    </div>
    <div id="tab-4" >
      Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
    </div>
</div><!-- container -->

In the above code I’ve created an unordered list which will act as tabs and I’ve used a custom attribute named data-tab and set its value to tab-1, tab-2 and so forth. We will use the data-tab attribute in our jQuery script to toggle the “current” class to hide and display our tabs.

Below the unordered list, there are a few DIV elements with ID attribute same as the data-tab attribute we used in the unordered list. This will do all the magic. Before adding the magic script, lets write some CSS to stylise our HTML Unordered list and content panels.

I’ve added “current” class to the first elements and we will play with the current class to stylise the active tabs and toggle the data content div element.

Step 3: Write some CSS to style the HTML

body{
	margin-top: 100px;
	font-family: 'Trebuchet MS', serif;
	line-height: 1.6
}
.container{
	width: 800px;
	margin: 0 auto;
}

ul.tabs{
	margin: 0px;
	padding: 0px;
	list-style: none;
}
ul.tabs li{
	background: none;
	color: #222;
	display: inline-block;
	padding: 10px 15px;
	cursor: pointer;
}

ul.tabs li.current{
	background: #ededed;
	color: #222;
}

.tab-content{
	display: none;
	background: #ededed;
	padding: 15px;
}

.tab-content.current{
	display: inherit;
}

I’ve used display:none for the .tab-content and display:inherit for the “current” tab. This will hide all DIV elements and show the tab with current class only. We will play with the current class to get our tabbed content work with a small magical jQuery code.

You can always change the CSS to have the look and feel similar to your website, use some image backgrounds to make it nice and smooth.

Step 4: Write the magic jQuery code

Now here’s the magic jQuery code which will actually create the tabbed content work.

$(document).ready(function(){
	$('ul.tabs li').click(function(){
		var tab_id = $(this).attr('data-tab');
		$('ul.tabs li').removeClass('current');
		$('.tab-content').removeClass('current');
		$(this).addClass('current');
		$("#"+tab_id).addClass('current');
	});
});

When the DOM is ready, if a user clicks on any list element of ul.tabs it will grab the data-tab attribute and assign the same to tab_id variable. Then, we will remove the current class from all list elements and our DIV.tab-content elements with the jQuery removeClass attribute. Then we will add the “current” class to the clicked list element and DIV tab with the grabbed data-tab ID.

That’s it, now we have working tabbed content with jQuery and CSS. Try it, share it and let me know of your thoughts in the comments. If you need to add any additional functionality, feel free to ask in the comments.

How to Create Pure CSS Accordion

In this tutorial, I’ll create a CSS Accordion without using any jQuery or Javascript. As I mentioned in my previous post “An easy way to create Tabbed Content with jQuery & CSS” displaying a lot of information on one page is a bit difficult and we can use tabbed content or accordions to achieve the same without compromising on user experience.

We can always use jQuery to include nice effects on our css accordion. However, we are going to create a pure css accordion that will work on any browser, with or without javascript enabled.

Lets start with writing some HTML Code. We will use UL (unordered list) element to create our pure css accordion.

HTML Code for pure CSS Accordion:

<ul id="accordion">
  <li>
    <h2>Title One</h2>
    <div >
      Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
      tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam.
    </div>
  </li>
  <li>
    <h2>Title Two</h2>
    <div >
      Tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam,
      quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo.
    </div>
  </li>
  <li>
    <h2>Title Three</h2>
    <div >
      Quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo
      consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse.
    </div>
  </li>
  <li>
    <h2>Title Four</h2>
    <div >
      Consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse
      cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non
      proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
    </div>
  </li>
</ul>

As you can see, I have a UL element and added a class named “accordion”. Within the LI element, I have H2 and a DIV tag with class “content”. And we will play with the CSS display attribute to create our pure css accordion.

Lets write some CSS code to stylise the same and hide our DIV.content within the LI tags.

CSS Code for pure CSS Accordion:

#accordion{
    width: 600px;
    margin: 0px;
    padding: 0px;
    list-style: none;
}
#accordion h2{
    font-size: 12pt;
    margin: 0px;
    padding: 10px;
    background: #ccc;
    border-bottom: 1px solid #fff;
}
#accordion li div.content{
    display: none;
    padding: 10px;
    background: #f9f9f9;
    border: 1px solid #ddd;
}
#accordion li:hover div.content{
    display: inherit;
}

As you can see in above code, we have used display: none for the div.content and on li:hover we have used display:inherit . The div.content is within the list element so this trick would work. If our div.content would have been outside this panel, we would have used jQuery to achieve the same.

Very soon, I’ll explain to achieve the same with jQuery and will use some nice animation as well.

jQuery CSS Class playground

Today we will play with jQuery CSS class methods such as addClassremoveClasshasClass, and toggleClass and learn some basic implementation to modify the HTML styles on the fly.

jQuery CSS Class Methods:

Let’s understand this is a small piece of code. First things first, You must include the jQuery library in the <head>…</head>  tag.

<script src=PATH_TO_JQUERY/jquery.min.js></script>

Now our page has the jQuery library so let’s add some HTML and CSS to play with the jQuery CSS Class methods.

HTML Code:

<div id="elem">
  This is a content panel
</div>

<p>
  <a href="#" >addClass</a> /
  <a href="#" >removeClass</a> /
  <a href="#" >toggleClass</a> /
  <a href="#" >hasClass</a>
</p>

Here we have a DIV tag with ID set to element and we will use this ID to play with jQuery CSS class methods. Below that, we have a paragraph element and four links with different class names. Let’s write some CSS code and I will explain the functionality of each link when we add jQuery code.

 CSS Code

#elem{
	width: 400px;
	text-align: center;
	padding: 20px 0;
	background: #ffffff;
	border: 1px solid #ddd;
	margin: 100px auto 30px auto;
}

.hover{
	background: #cc0000 !important;
	color: #fff !important;
	border: 1px solid #990000 !important;
}

In the CSS styles, I’ve added some styles to our DIV#elem element and also created a class named hover which will change the background, color, and border of the DIV#elem.

Now let’s add some jQuery code and learn how these jQuery CSS methods work.

$(document).ready(function(){
	// Add the class
	$('a.add-class').click(function(){
		$("#elem").addClass('hover');
		$("#elem").html('Class added ".hover"');
		return false;
	});

	// Remove the class
	$('a.remove-class').click(function(){
		$("#elem").removeClass('hover');
		$("#elem").html('Class removed ".hover"');
		return false;
	});

	// Toggle the class and check if the class has been already added or not
	$('a.toggle-class').click(function(){

		$("#elem").toggleClass('hover');

		if($("#elem").hasClass('hover')){
			$("#elem").html('Class added ".hover"');
		}else{
			$("#elem").html('Class removed ".hover"');
		}

		return false;
	});

	// Checks if the class has been already added or not
	$('a.has-class').click(function(){

		if($("#elem").hasClass('hover')){
			$("#elem").html('Class found ".hover"');
		}else{
			$("#elem").html('Class not found ".hover"');
		}

		return false;
	});

});

In the JQuery code, I’ve used the click trigger for all four links we added in the HTML code above. Also, I’ve used return false;  so when we click on the link it should not redirect the user to any page or use # in the current page URL. Also, I’ve added another line of code to modify the HTML of the #elem element when we click on these links. Don’t get confused with the .html() method, this is not required, I just added it to explain the functionality.

The first link with class .add-class will add the .hover class to the #elem element. If you want to add multiple classes with one trigger you can specify different class names separated with a space as we normally do in normal HTML code. Once we click on this link, .hover class will be added to the #elem HTML element and the inner HTML will be changed and show us the result. You can click on the address link above and see it in action.

The second link with class .remove-class will remove the .hover class from the #elem element. If the element doesn’t have a .hover class, it won’t do anything so the remove class will be used only to remove any applied class.

The third link with class .toggleClass will toggle the .hove class on #elem element. If the element does not have a .hover class it will add the same otherwise vice versa. In this code, I’ve used the jQuery CSS method hasClass to check if the element has the .hover class or not. and the content of the #elem element is changed accordingly.

The fourth link will only check if the class .hover is applied to the #elem element or not and change the HTML code of the #elem element accordingly.

I hope this will clarify any doubts on using these methods, in case you have any questions or suggestions, please use the comments below to start a conversation on this topic.

CSS3 Animation – Stylish Links and other HTML elements

Links, Links, Links!! That’s what we have all over the internet. On our website and blog posts, we have a lot of links to point a user to another page. Today I will share a small trick to stylize the links with CSS3 Animation. That’s what I’ve used on this website and you can apply the same as well to change the link color with style on hover.

CSS3 Animation

With CSS3 animation, we can add some effects when changing from one style to another without using any flash or javascript. We will use CSS animation transition to add some cool effects to the anchor tags.

How it works

CSS3 transition effects let an element gradually change from one style to another. To do this we must specify two things:

Specify the CSS property we want to add an effect too.
Specify the duration of the effect.
Optionally we can specify “transition-timing-function” which is set to “ease” by default however, we can use any of these.

 linear|ease|ease-in|ease-out|ease-in-out

Now let us play with CSS3 Animation transition

HTML Code

<a href="#" title="" > CSS3 Animation - Color </a>
<a href="#" title="" > CSS3 Animation - Background Color </a>
<div > Change Width </div>

CSS Code

.color-animation{
	color: blue;
	-webkit-transition: color 1s ease;
	-moz-transition: color 1s ease;
	-o-transition: color 1s ease;
	-ms-transition: color 1s ease;
	transition: color 1s ease;
}
.color-animation:hover{
	color: red;
	-webkit-transition: color 1s ease;
	-moz-transition: color 1s ease;
	-o-transition: color 1s ease;
	-ms-transition: color 1s ease;
	transition: color 1s ease;
}
.background-animation{
	background: blue !important;
	color: white !important;
	-webkit-transition: background 1s ease;
	-moz-transition: background 1s ease;
	-o-transition: background 1s ease;
	-ms-transition: background 1s ease;
	transition: background 1s ease;
}
.background-animation:hover{
	background: red !important;
	color: white !important;
	-webkit-transition: background 1s ease;
	-moz-transition: background 1s ease;
	-o-transition: background 1s ease;
	-ms-transition: background 1s ease;
	transition: background 1s ease;
}
.change-width{
	width: 150px;
	background: #444;
	color: #fff;
	margin: 20px auto;
	padding: 10px;
	-webkit-transition: width 1s ease;
	-moz-transition: width 1s ease;
	-o-transition: width 1s ease;
	-ms-transition: width 1s ease;
	transition: width 1s ease;
}
.change-width:hover{
	width: 350px;
	-webkit-transition: width 1s ease;
	-moz-transition: width 1s ease;
	-o-transition: width 1s ease;
	-ms-transition: width 1s ease;
	transition: width 1s ease;
}

Try this code on a blank HTML page and add the CSS either within ... tags or in your stylesheet. Play around a bit with the CSS to understand the CSS3 Animation transition and create some cool effects for your website links and other block-level elements. Feel free to discuss this further in the comments. You can also contact IOGOOS Solution to build Website Animation Services.

Google Web Fonts – How to Use, Download, and Sync

Typography is the key element in the design process. While designing a web page, business card, brochure or newspaper advertisement fonts and text style plays an important role to get user attention. To design stunning elements we need fonts and fortunately, the big daddy provides a lot of them for free. We can use Google Web Fonts in our designs and they are pretty awesome and very easy to use.

How to use Google Web Fonts on a web page

It’s pretty easy to use Google Web Fonts on your website. You can do that in just three simple steps:

  1. Choose single or multiple Google Web Font(s) from Google fonts website: //www.google.com/fonts and add them in your collection.
  2. Hit the use link above the list of your selected fonts and Google will show you different methods to include these fonts on your website. Standard, @import or Javascript
  3. I always use Standard method with a small trick to load the fonts before displaying the web page.

Here’s the code you would need to use Google Web Fonts on your website.

I’ve added Open Sans and Lobster fonts to my collection for this example.

<head>
<link href='//fonts.googleapis.com/css?family=Lobster|Open+Sans' rel='stylesheet' type='text/css'>
<!-- This will prefetch content from google web fonts website -->
<link rel="dns-prefetch" href="//fonts.googleapis.com" />
</head>

The above code goes within the [htmltag tag=”code”]<head>…</head>[/htmltag] tags and the DNS-prefetch link tag will fetch the contents from Google Web Fonts website. This will help resolve issues like font changes after the page load.

body{
    font-family: 'Open Sans', sans-serif;
}
h1, h2, h3, h4, h5, h6{
    font-family: 'Lobster', cursive;
}

In the above CSS code, I’ve defined the body font as open sans and headings font as lobster. Similarly, you can use different fonts for different elements.

How to Use Google Web Fonts while Designing?

As a designer, we all need to design the mockups of the creative work before we can publish the same. If we need to use Google Web Fonts while designing layouts in Photoshop or Illustrator we will have to download the font and install the same in our Operating System.

We can always click the Download link to save the fonts on our hard drive and then install the font on our operating system. However, what will happen if that font is updated and new characters are added or there’s a new and improved version available for that font. We need to keep a check and if the new version is available, we need to uninstall the previous version and then install the new version.

What is there’s some tool which can automatically do this task and save us a lot of time and effort?

Fortunately, there are tools available that can make our life easy and keep Google Web Fonts updated all the time.

Using Skyfonts to Download and Sync Google Fonts

Fonts.com has teamed up with Google to offer google web fonts for desktops via Skyfonts software.

We are proud to have teamed up with Google to offer desktop versions of their popular Google Fonts free of charge. Offered for use in print, these fonts are delivered using SkyFont’s patent-pending font delivery technology and can be used anywhere.

Each time a font is updated — such as when new characters are added — SkyFonts will automatically update the font on your device. Syncing Google Fonts with SkyFonts will also improve your web browsing experience, by cutting the time spent downloading fonts. ~ Fonts.com

Skyfonts software is available for both Mac and Windows. You can choose the fonts you want to use while designing and Skyfonts sync these fonts with your operating system fonts and make them available in all applications as normally installed fonts. If a new version of the installed font is available, the Skyfonts application will automatically sync and replace the older one with the new version.

Download Skyfonts Software

There are other methods available to download all Google Web Fonts on your computer, however, I found Skyfonts the easiest and most efficient to keep all the fonts updated.
