html development

CSS 2was developed by the W3C and published as the superset of CSS1, CSS2 includes a number of new capabilities like absolute, relative, and fixed positioning of elements and z-index, the concept of media types, support for aural style sheets and bidirectional text, and new font properties such as shadows. CSS level 2 fixes errors quite smoothly, removes poorly-supported features and adds already-implemented browser extensions to the specification.

Since CSS2 was introduced, there’s been some discussion as to what it should encompass, who should be responsible for the spec and what it should be called etc but W3C officially recommended it for developing websites and from then it is accepted worldwide. The optimal solution would be communication between developers and browser makers. Whet ever features it includes but the most important features would be including cross browser friendliness. The most important feature of CSS2 is its multiple background images; along with that customized and preferable background clip, origin and size are also there. Border images are also there, as it would do an agreement on implementation of border radius.

CSS level 3 is currently a rage among the designers. CSS3 is modularized and will consist of several separate recommendations. There are many benefits of using CSS3 for the clients of your website.

In CSS3 also we have found some of the new properties such as corner radius, RGBA color, box shadow and gradients offer material benefits when implementing designs - less time is required in adding superfluous markup and preparing assets. So delivery of the website can be really faster.

In addition, using CSS3 instead of image assets can yield some fairly significant performance improvements - less HTTP requests, faster download. This is especially important when building for mobile, where the major platforms all have browsers with decent CSS3 support. Other CSS3 features, like animation, 2D and 3D transforms, transitions are equally attractive when development is done using CSS3.
