Default WP gallery trouble

[logoglo]

HI there, I have a default wordpress gallery setup:

http://txadproofs.com/columbusjellystone.com/gallery/

How do I center it?

How do I reduce the padding between the thumbnails?

How do I make the thumbnails bigger? (Itried in the media setting of WP but they dont change)

Thanks.

This is driving me crazy, here too:

In theory it should center right? and fill the content bar?

Hi There,

Please try adding the following CSS under Customizer > Custom > Global CSS:

.gallery .gallery-item {
    float: none;
    display: inline-block;
    margin: 2% 2% 0 0;
}

After that adding the size attribute to your gallery shortcode, something likes this:

[gallery ids="729,732,731,720"]

Let us know how it goes!
