Hello.

To import a CSS style sheet, there are several ways in which it:

PHP Code:

@ Import url(Style. Css) screen; 


But I see almost nobody used it.

I would use it.

But before that, I know if it was a technique obsolete or soon will be?



In terms of utility, is when you have several designs, there are classes that do not change as:

PHP Code:

del / * For content deleted * /
{
    text-decoration: line-through;
}

. Center
{
    text-align: center;
}

. Red
{
    color: red;
} 


Thank you.

You can still use it, but it does present some problems, the most notable of which is FOUC - the "flash of unstyled content" which occurs during the delay it takes to import the css file.

It is better to combine all CSS files you are using. Once the file is cached the server responds with 304 and you save bandwidth

@import is not recommended, as LadynRed said.

Google Page Speed also says "Avoid @import CSS"

@import was only used so that really old browsers (like Netscape 4.x) would ignore the CSS it couldn't handle. Even if you are, for some reason, developing for these older browser there are better methods of browser selection available.

I don't really see the point in using this myself. I've seen it used even recently on a wordpress template I was installing for someone. They had 1 style sheet with nothing in it but a clearfix, and 6 Imports...

Major FOUC...
