Cascading Style Sheets (CSS) has gained enormous attention from the web designers of all around world. It is basically used for describing various properties of web page written in HTML and helps to make them more appealing and eye catchy. It generally contains information about layouts, colors, fonts as well as can help you to modify the contents of whole web page easily.
Back in the day, when CSS was not around, use of tables in HTML used to be a pain. Tables used to make the web pages and web designs very heavy, resulting in slow loading of the website, incompatible with most browsers, hence, leaving a narrow choice for the visitors to avail the website.
Today, developing HTML into CSS gives a different feel to the web design and some extra features along with it. It improves the page loading time due to reduced size of code file. It became now browser friendly and SEO friendly as well. Due to its systematic and clear coding style, it offers less complex web content structure which in turn helps search engines to easily locate the required contents and keywords during search. Not to mention mobile users now can easily access websites designed using CSS compare to traditional websites with table structure.
CSS has various levels and profiles. Each level of CSS builds upon the last, typically adding new features and typically denoted as CSS 1, CSS 2, CSS 3, and CSS 4. (Profiles are typically a subset of one or more levels of CSS built for a particular device or user interface.)
Google Trends result proves that among these CSS levels, CSS3 seems to be the most reliable one. Apparently, CSS 2 has become less popular now. CSS 4, on the other hand, has been not so popular since it is currently not supported by any major web browser.
CSS 3 is divided into several separate documents called “modules” — each module adds new capabilities or extends features defined in CSS 2, over preserving backward compatibility.
The consistency of web pages throughout the website is important so as to make alterations possible to the web page elements. And it’s been proven that it is much easier to maintain, handle and control the whole website made on CSS based HTML/XHTML. So next time, whenever you think about getting HTML or XHTML Web Design work done, don’t forget to keep CSS in mind.
