CSS3 variables causing issues

I want to streamline my CSS file by setting up generic variables that can be used throughout to ensure consistency and organization.

For example:

@shadow: 6px 6px 10px rgba(0,0,0,0.2);

.shadow {
    box-shadow: @shadow inset;
}

However, when I try to apply .shadow to an element, the shadow does not appear on the page. Upon inspecting the Elements in Chrome, I notice that .shadow is crossed out with the message "Invalid property value".

This issue extends beyond just shadows; it also occurs with properties like width and height.

I have seen similar setups work perfectly fine on JSFiddle pages in the same browser, so I don't believe the problem lies with the browser itself.

Answer №1

When it comes to declaring variables, CSS pre-processors such as LESS or SASS are the way to go. Unfortunately, CSS3 does not support variable declaration rules.

If you're seeing variables in your JSFiddle pages, chances are you have included these pre-processors which could be causing some confusion.
