Apparently this trick has been around for a loooooong time, but I only just learned of it. So I’m pretty sure there are others who will benefit from it as well.
So, let’s say you have a div that looks something like this:
<div class="something" style="background: #999;">Stuff</div>
Maybe this is a div created by a plugin and it inlines those styles through some options on the backend, or you just don’t have access to make changes to the theme files directly. This is a nifty little trick you can use:
div.something[style] { background: #678696 !important; }
That’s all there is to it!
Let me know in the comments below if this helped you or if you’ve had any difficulties getting it to work.
