Trouble with custom button color

Kindly refer to the FAQ which states:

There is a textbox on the plugin settings page where you can enter your own CSS class name. This will be appended as follows:

• For color buttons, the class will be scbb-button-whatever you typed
• For boxes, the class will be scbb-content-box-whatever you typed

You must supply the matching CSS for your custom class.

So you need to use a word and then add the corresponding CSS to your local CSS file. Ex: put “black” into the textbox and the name of the class will be “scbb-button-black”. Then put the CSS you want for the button in your local CSS file, ex:

.scbb-button-black { /* your CSS markup here */ }
