External CSS Scripts

When utilizing CSS it is preferred to maintain the CSS separate from your HTML. Puting CSS in a separate file allows the web interior decorator to wholly distinguish between content ( HTML ) and design ( CSS ) . External CSS is a file that contains merely CSS codification and is saved with a `` .css '' file extension. This CSS file is so referenced in your HTML utilizing the & lt ; link & gt ; alternatively of & lt ; manner & gt ; .

Advantages

It keeps your website design and content offprint.

It 's much easier to recycle your CSS codification if you have it in a separate file. Alternatively of typing the same CSS codification on every web page you have, merely hold many pages refer to a individual CSS file with the `` nexus '' ticket.

You can do drastic alterations to your web pages with merely a few alterations in a individual CSS file

The @ import CCS regulation allows the user to import regulations organize other manner sheets. This manner the users can avoid retrieving resources for unsupported media types. After the URL these conditions imports comma separated media quires. If these are no media query the import will be unconditioned.

@ import url list-of-media-queries ;

URL Is a & lt ; threading & gt ; or a & lt ; uri & gt ; stand foring the location of the resource to import. The URL may be an absolute or comparative url.list-of-media-queries Is a comma-separated list of media questions conditioning the application of the cesium regulations defined in the linked URL.

I used milliliter book because I created a little web site which consist of few pages. So even if I have to infix a new CSS page I do n't hold to travel through all the pages. I did non utilize @ import because we have to look into our web site on different browsers. I want my web site to work on chief browsers such as internet adventurer, Firefox and Google chrome.
