html - how to overwrite css style

Question

I'm developing pages, now in my css style I have this line of code

.flex-control-thumbs li {
    width: 25%;
    float: left;
    margin: 0;
}

for my pages. Now, some of my pages don't need this line

width: 25%;
float: left;

It is possible that I can overwrite it in internal css of the page, which will cause the original behaviour to be ignored?

Answer 1

Using !important is not recommended but in this situation I think you should -

Write this in your internal CSS -

.flex-control-thumbs li {
  width: auto !important;
  float: none !important;
}
