Before I try that, I’m thinking this doesn’t give me the settings of color and width, etc,
You can just edit the code I provide to suit your need:
border: 2px solid #fff;
2px
is the border width.
solid
is the border style.
#fff
is the color.
Which means Generatepress doesn’t have a section that gives you control over photo presentation, am I right?
That is correct.
Can you start by adding the code I provided then we can go from there and make the adjustments if needed?
