php - Commenting in Dynamic CSS

Question

I'm working with a dynamic stylesheet, ie: style.php, beginning with the code

<?php header('Content-type: text/css'); ?>

How should I comment in such a file?

From my own experience, html style commenting tends to cause some trouble (deactivating upcoming styles) whereas css style commenting tends to be ignored.

On the other hand, Notepad++ colors the html comments green, while leaving the css comments black.

Anyway, if there's an official answer, or some special rules, I'd like to know.

Thanks.

Answer 1

如果您希望注释出现在生成的 CSS 中，请使用 CSS 注释，如下所示：

echo "/* My css comment */";
echo "body { margin: 0 }";

如果您不希望它们在生成的 CSS 中可见并且只希望在编辑 PHP 文件时能够读取它们，请使用常规 PHP 注释：

// Just a regular PHP comment, this won't be visible in the generated CSS!
echo "body { margin: 0 }";
/* You can use this style of comments too, it's up to you what you prefer. */

Answer 2

<?php
    header('Content-type: text/css');

    echo "* { margin: 0; }";
    // Comments 1
    # Comments 2
    /* Comments 3 */
?>
