How to remove Image Padding and Borders?

When asking CSS questions, which btw isn’t just the matter of this forum, a URL to the page with the problem is necessary

For individual images you can add:

border-width: 0px; padding: 0px;

to the image properties in the wordpress visual editor.

Hi Ed,

Like john said, you should add this to your child theme style.css file.
And to override the default, you should try to get specific selector and follow is 2 declaration

border-width: 0;
padding: 0;
