- rather than flashing a colour when hovering on top of the box, is it possible also to have some posts/boxes show a static colour-frame?
You can set a static background color for all the boxes at once with this CSS:
.box .texts {
opacity: 1 !important;
}
The boxes don't have unique identifiers, so they are not easily targeted but it might be possible to force one of the boxes to get highlighted using CSS3 pseudo selectors. The down side is that this code doesn't work in Internet Explorer. Also, it doesn't seem to want to obey the nth-child selector rules. You can see an example using this CSS though:
.texts:nth-child(2n+2) {
border: 20px solid red !important;
background: red !important;
opacity: 1 !important;
}
