Can a <style> tag be included in a .css file without issue?

Within one of our projects, there is a <style> tag placed at the beginning of a CSS file (for the purpose of ensuring CSS highlighting in certain text editors):

<style>
body {
  ...
}
....

Although I am aware that this is considered incorrect within a CSS file as it typically signifies inline CSS within HTML, it appears to be accepted (at least by Firefox 49) when the <style> tag is placed inside the CSS include file at the start.

I am currently investigating whether it is necessary to rectify this in our project or if it can remain unchanged, especially if it is widely accepted (particularly by Firefox since version 26).

Answer №1

This response does not directly address the question, however...

The CSS provided is not considered valid. Delete it. Delete it immediately.

Although it may currently be accepted, there is no guarantee it will be in the future. There could be a new specification where certain tags in a CSS file have special meanings. It may be unlikely, but one never knows.

In the world of web development, we already resort to hacks to handle various browser quirks. The creation of jQuery itself was based on this principle, not to mention hacks like clearfix and browser resets. Introducing a hack to support an editor seems like a risky idea.

If I were in charge of this team, I would insist that any editor is acceptable (from a pre-approved list) as long as it is able to work with valid code.

Answer №2

It seems there is some confusion in understanding your question. Just remember that you do not need to include the "style" tag in your CSS file. If it is a .css file, simply write your CSS code without the need for the "style" tag. However, if you are adding CSS code to a PHP or HTML file, make sure to begin with the "style" tag and end it within the head section. This is a fundamental concept!
