Look of Single Post category

Yes, category terms are okay but I wanted to set an outline border for the category terms. Not for the border around the post content.

However, the current one looks good. No need to change now. Thanks for your support.

If you want the purple boxes to have borders, you can do this:

.cat-links a {
    border: 1px solid purple;
}

Yes. Now, it's perfect. Thanks a lot.

You're welcome :)
