You just have to activate the plugin and go building your posts, pages or projects; you will find in the Divi Audio module some new design options both under the ‘Content’ tab (‘Audio Timeline Margin’ setting under ‘Audio’ toggle and ‘Image Width’ under ‘Image’ toggle) and in the ‘Design’ one (here you will find at the top a new ‘Audio’ toggle to customize timeline colors and other).

This utility plugin adds a series of css classes that allow easy addition of set padding and margin to any element.
For basic use, the classes follow the format of [margin / padding][location letter: all, top, right, bottom, left, vertical, horizontal][amount: none, small, medium, large, extra large (0.5em, 1em, 2em, 4em)]
Also in the basic classes are percentages, taking the place of the last letter in the format [p][percentage] e.g. p7-5 for 7.5% or p15 for 15%.
Examples of Basic Classes:
<ul>
<li>man > margin all none = margin: 0px;</li>
<li>prl > padding right large = padding-right: 2em;</li>
<li>mvp5 > margin vertical 5% = margin: 5% 0;</li>
</ul>
Additional utility classes – First / Last child, Child / Sub
To add selective classes for adding margin / padding to the first / last child, any child, or any sub-element of the required element, simply add ‘last-‘, ‘first-‘, ‘child-‘, or ‘sub-‘ to the beginning of the basic classes.
Examples of Child Classes
<ul>
<li>last-mhxl > last-child margin horizontal extra large = last-mhxl :last-child { margin: 0 4em; }</li>
<li>last-pbn > last-child padding bottom none = last-pbn :last-child { padding-bottom: 0; }</li>
<li>first-mtm > first-child margin top medium = first-mtm :first-child { margin-top: 2em; }</li>
<li>child-mal > child margin all large = child-mal > * { margin: 4em; }</li>
<li>sub-php5 > sub elements padding horizontal 5 percent = sub-php5 * { padding: 0 5%; }</li>
</ul>
Additional utility classes – Responsive margin / padding
You can also apply the margin / padding required to certain screen widths, ranging from xl (min: 1200px) to xs (max: 480px). To use these responsive classes, add -[screen-size] to the end of the basic classes.
Examples of Responsive Classes
<ul>
<li>mrm-lg > margin right medium, large screen = (max-width: 1199px) and (min-width: 980px) margin-right: 2em;</li>
<li>pas-xs > padding all small, xsmall screen = (max-width: 480px) padding: 0.5em;</li>
<li>mhp15-md > margin horizontal 15%, medium screen = (max-width: 979px) and (min-width: 768px) margin-left: 15%; margin-right: 15%;</li>
</ul>
