Changes to styles.css Don't Effect Website?

I’m trying to change the width of the images so they are full width like this:

.td-post-content img,
.mce-content-body img {
margin-bottom: 21px;
width: 100%;
}

But nothing happens when I save style.css.

Even if I remove everything in style.css and save the file the website still looks like the styles from style.css are being applied. What am I doing wrong?

Hi

I’ve checked the code you provided and works fine: http://screencast.com/t/43EUeFXVkUdb – http://screencast.com/t/nxohKCX4 Try to clear all caches and test the code again. If the problem persist please provide your site url so I can inspect it closer.

Thanks!
