Adding border

Hi @dimitriosvasileiou
you’re welcome!

Adding a CSS border is simple. The following style applies a 1px black border around the entire widget:

.widget.posts-in-sidebar {
background-color: #fff;
border: 1px solid #000;
padding: 1em;
}

If you don’t see the border, surely your current theme should have a rule that is applied after. In this case, tell me the URL of your site so I can help you better.

Let me know, please.

Perfect, thank you very much.
