customize post's sticky view

Hi, the theme uses the class .sticky for sticky posts.
Just find the css selectors you need for thumbnails and read more by opening your browser dev tool and make them more specific (from a css standpoint) with the .sticky classes placed before.
Hope this helps!

I have found .entry-summary but no .sticky.

None of your posts seem to be sticky … ?

Do you simply mean on the blog post list? If so, then take nikeo’s advice above, but place the .blog class before.

For example, to make the images rectangular, add:

.blog .round-div {
    display: none;
}

Or alternatively, if you still want them round, you can increase the non-hovered size with:

.blog article .round-div {
  -webkit-transform: scale(1.2);
  -moz-transform: scale(1.2);
  -ms-transform: scale(1.2);
  -o-transform: scale(1.2);
  transform: scale(1.2);
}

oh yes i meant on the blog post list ! Sorry to explain wrong, English is not my mother tongue and css even less! ??
The round shape is ok but do you know how I can enlarge the pictures on this page and add a “read more” button ?

I’ve answered how to enlarge above.

Yes you answered above how to enlarge the round effect but i’m looking to enlarge the picture under. ??
