Remove white borders around images after upgrade

Replies: 1

After today’s evolve update, the white borders around my images have “re-appeared”.

I had already got the following code in my css which successfully removed the borders previously:

.entry-content img, .entry-content .wp-caption {
box-shadow: none;
padding: 0px;
border: none;
}

I tried adding the following code (as mentioned in another thread) but to no avail:
.entry-content img, .entry-content .wp-caption {
background: transparent;
}

Any help is gratefully received.
Many thanks,
Rachel
