Eliminating duplicate CSS properties from multiple CSS files can help streamline your stylesheets

I am dealing with a situation where I have two CSS files containing redundant CSS properties.

For example, in foo.css:

#test {
    border: 0;
    font-size: 16px;
}

In bar.css:

#test {
    border: 0;
    font-size: 32px;
    width: auto;
}

My goal is to remove the duplicate border: 0; from bar.css.

I thought this issue would have been addressed before, but surprisingly I couldn't find a solution anywhere. Isn't there a handy tool that can help streamline this process of comparing and modifying multiple CSS files?

Answer №1

If you're using Firefox, there's a handy extension called Dust-Me Selectors that can help you identify which stylesheets are being used and which ones are not.

This tool can be valuable in cleaning up your CSS and removing unnecessary styles. However, it's important to use some discretion as certain styles may appear unused but are actually needed for dynamic elements on the page.
