Understanding Cascading Style Sheets
Cascading Style Sheets (CSS) are a series of formatting rules that control the appearance of Web page content. When you use CSS to format the page, separate the content from the presentation. The content of the page (that is, the HTML code) resides in the HTML file itself, while the CSS rules used to define the code representation reside in another file (the external st

The Code is as follows:This effect

advantages of parallel download components are obvious. Then, when the script is downloaded, the parallel download is actually disabled (even if a different host name is used, the browser does not start another download.) One reason is that the script might use document.write to modify the contents of the page, so the browser waits to ensure that the page is properly laid out.
