I’ve seen this before with some of the older Genesis child themes.
The stylesheet of your theme is overriding the rules in the tabby stylesheet so the padding values do not take effect. The #content ID seem to be the culprit eg
#content .post ul, #content .page ul {
list-style-type: square;
margin: 0;
padding: 0 0 15px 0;
}
#content .post ul li, #content .page ul li {
list-style-type: square;
margin: 0 0 0 20px;
padding: 0;
}
To remedy this you can replace the tabby stylesheet as described in the plugin’s documentation and edit the rules to increase the specificity.
Adding #content
to the rules that are not taking effect should do it.
eg:
#content .responsive-tabs .responsive-tabs__list {
font-size: 18px;
line-height: 18px;
margin: 20px 0 10px 0;
padding-bottom:0;
}
#content .responsive-tabs .responsive-tabs__list__item {
border: 1px solid transparent;
border-bottom: none;
line-height: 1;
margin: 0 14px 0 0;
padding: 10px 20px;
}
Some other rules will probably also need similar tweakage.
