CSS has been developed for the first time in 1997 as a way for Web developers to define the appearance of their Web pages. It is intended to allow developers to separate content of the HTML design so that can carry over the function it was originally founded on - the markup content, regardless of the design and layout.
CSS has not gained popularity in the mid 2000, when Web browsers began using more of the basic police and color aspects of the SSC. And now, all modern browsers support all CSS level 1, most CSS level 2, and some aspects of CSS level 3.
The Web designers who do not use CSS for the design and development of Web sites are becoming a thing of the past. And it is undoubtedly also important to understand that CSS is to know HTML - and some would say it was more important to know CSS.
CSS is an abbreviation, It means Cascading Style Sheet.
Stylesheet refers to the document itself. The style sheets were used to design documents for years. They are the technical specifications for a layout, whether print or online. Print designers use style sheets to ensure that their designs are printed exactly to specifications. A stylesheet for a webpage serves the same goal, but with additional features also display engine (the browser) explains how to make the document being viewed.
Cascade is the special part. A stylesheet Web is intended to cascade through a series of style, like a river over a waterfall. The water in the river all the hits rocks in the waterfall, but only those at the bottom affect exactly where the water will flow. The same is true of the cascade in Web style sheets.
Each Web page is affected by at least one stylesheet, even if the Web designer does not apply to all styles. This stylesheet is the agent user stylesheet - style default Web browser uses to display a page if no further instructions are provided. But if the designer provides further instructions, the navigator must know what instructions have priority.
For example, in my Web browser, the default font is Times New Roman size 16. But nearly no pages I visit in the display are the family and size. The reason is that the second cascade defines style sheets set by the designers to redefine the font size and family take precedence over my default Web browser.
Where is CSS used?
CSS is used to the style of Web pages. But it is more than that. CSS is used to the style XHTML and XML. This means that anywhere you have tagged in XML (including XHTML), you can use CSS to define how it will be.
CSS is also used to define how Web pages should look seen in other media as a Web browser. For example, you can create an impression stylesheet that define how the Web page must be printed and another stylesheet to view the Web page on a projector for a slide show.
CSS Why is it important?
CSS is one of the most powerful tools a Web designer can know it because you can affect the whole mood and tone of a website. While writing style sheets can be updated quickly sites and help change what is in order of priority or value without changing the underlying XHTML. T
he challenge of CSS is that there is so much to learn. But it does not seem like her. After all, there are only about 60 properties in CSS level 1 and around 70 in CSS level 2. In comparison with the number of HTML tags and attributes to learn, which can feel like a cake walk.
But because CSS may cascade, and combine and browsers interpret the guidelines differently, CSS is more difficult than HTML. But once you start using it, you will see that harnessing the power of CSS will give you more options and allow you to do more things with your Web sites.
If you want to be a professional Web designer, you must learn Cascading Style Sheets. But fortunately, they are fun to learn.
