how to add custom style?

The custom style section should be viewed as a CSS stylesheet for collapse-o-matic plugin.

Some examples of how I’ve used it include assigning ID’s to certain expand collapse shortcodes and then modifying the CSS.

Example:

[expand title="My Title" id="example"] This is my content [/expand]

Then in the custom style section:

#example { background-color: red; height: 50px; }

Hope this helps!

ID’s should be unique for each element. Rather than use the id to define the css, use the trigclass class like so:

[expand title="My Title" id="example_01 trigclass="my_class""] This is my content [/expand]

Then in the custom style section:
.my_class { background-color: red; height: 50px; }

And that’s how the seahorse do!

So that’s how you use that properly! Silly me. Thanks so much for clarifying this!
