Styling HTML 5 elements with Modernizr, Better HTML5 & CSS3 Usage By Detecting Browsers Capabilities

Similar to the IE6 situation, when using HTML5/CSS3 in our websites, it is a good idea to offer non-problematic outputs to web users with older/non-standard browsers.

Modernizr is a JavaScript library that uses feature detection techniques to determine whether or not the current browser is capable of CSS3 and HTML5 features like rgba(), border-radius, CSS Transitions & more.


It enables you to write pseudo-IF/ELSE statements in your CSS &, if wanted, it is possible to wirite conditional statements in JavaScript with the help of a “Modernizr JavaScript object” created.

Also, Modernizr adds support for styling HTML 5 elements. This allows you to use more semantic, forward-looking elements such as <section>, <header> and <dialog> without having to worry about them not working in Internet Explorer.

Best New Essential CSS3 Techniques Revealed

This article presents 7 New CSS3 techniques that every web designer and developer should be aware of. CSS3 for sure will leads to greater flexibility and make effects that was previously complex and difficult to create much easier. Unfortunately it is not currently all the leading browsers that support CSS3. In some cases other techniques are available making our life easier while waiting for CSS3 to break through and these will be briefly covered as well.

Be aware that CSS3 features are not yet accessed directly in most browsers and in some it is not even implemented at all, ex. Internet Explorer. Firefox use a prefixed with -moz-, resulting in fx. -moz-box-sizing. Safari 3 / WebKit uses -webkit-box-sizing and Opera just accepts plain box-sizing. Coding CSS3 is therefore currently a bit irritating as you have to write the same code multiple times with different prefixes. Anyway playing with and understanding the oppertunities that new features in CSS3 will offer is is worth investing a bit of your time for.

Border Radius: Create rounded corners

There are many ways to create rounded corners on boxes. The simplest techniques rely on the addition of extra mark-up directly to your page, while the more complicated ones add the mark-up though DOM manipulation. While most of these techniques are interesting to investigate, they are not really elegant. The strength and main goal of CSS is to separate content from presentation, yet using these techniques we are adding “unnecessary” mark-up to our code in order to create a visual effect. The reason that all these creative techniques have been invented is simple. With CSS2.1 we can only assing a single background image per element.

The good news is that W3C has offered some new options in CSS3. With CSS3 you’ll be able to add not one, not four, but eight background images to a single element. This means you’ll be able to create all kinds of interesting effects without the need of those additional elements. CSS3 is also adding border-radius that may eliminate the need for images to create rounded corners in most cases. Both Mozila/Firefox and Safari have implemented this new function, it’s not supported in any IE yet. Below you will see an example:

<div style=" background-color: #ccc;
-moz-border-radius: 5px;
-webkit-border-radius: 5px;
border: 1px solid #000;
padding: 10px;" >

Rounded Corner Boxes the CSS3 Way

While the CSS working group still seem to be arguing over the exact syntax, Dave Hyatt went ahead and implemented the currently suggested mechanism into Safari. The technique is fiendishly simple, and I think we’ll all be a lot better off once the W3C stop arguing over the details and allow browser vendors to get on and provide the tools we need to build better websites. corner

To create a CSS3 rounded corner box, simply start with your box element and apply your 4 corner images, separated by commas.

.box {
background-image: url(top-left.gif), url(top-right.gif), url(bottom-left.gif), url(bottom-right.gif);

We don’t want these background images to repeat, which is the normal behaviour, so lets set all their background-repeat properties to no-repeat. Continue reading

Backgrounds in CSS3

For the last part of our introductory series to CSS3, we will be taking a look at the new background properties. These include background size, using more than one background for an element, and background origin (which effects the position of a background).

The new features allow greater control of the background element and will provide designers with a whole array of new possibilities. As usual, examples can be found below:

Background Size

Before CSS3, background size was determined by the actual size of the image used. It will be possible with the next CSS revision to specify in terms of percentage or pixels how large a background image should be. This will allow you to re-use images in several different contexts and also expand a background to fill an area more accurately. Continue reading
