Custom CSS priority

This is the same issue i encounter using other plugins and the best way to tackle this is to prempt the class in your theme stylesheet with something from your theme.

e.g. being an iThemes Builder fan they have a class like

.builder-module .YOUR-plugin-class {
}

failing that use

body .YOUR-plugin-class {
}

no need to edit the plugin, just supersede the class. I’m unsure about the priority of CSS, and wondered this myself but the above is what is best practice.

body nearly always works as this is the beginning of the html document and is the very top most usable CSS selector.
