I'm trying to add custom css class to the sitecore Rich Text editor.

.infinityNumber .clickable {
        background-color: #00657c;
        color: white;
        padding: 0px 0px;

When selecting this class it only adds clickable class

<span class="clickable">test</span>

But I want like below. Can anyone let me know how to add like below,

<span class="infinityNumber clickable">test</span>

You can add a new CSS class in the Rich Text Editor dropdown and apply it to the selected row table.

There are two steps to add CSS class in RTE:

  1. Add element in Website\sitecore\shell\Controls\Rich Text Editor\ToolsFile.xml file.
  2. Now add the definition of that CSS class (eg. arrowlink) in Website\default.css file.

You can see newly added arrowlink CSS class in rich text editor dropdown. And apply this class wherever you want.
