CSS Utility Classes in Service Portal

Included with Service Portal are a variety of different CSS utility classes loosely based on some of Bootstraps utility classes.

For many of the classes below, you will see a format similar to: “m-t-lg”, this stands for “margin top large”. As I’m sure you can guess, there is also a classes for bottom, left, right, small (sm), medium (md), etc. and all the various combinations thereof.  This allows you to easily add consistent margins, padding, colors, etc. without creating custom styles within the widget.

Here is a list we’ve compiled of some of the most common utility classes:

  1. Hey Nathan –

    I’ve had issues using some of these classes in Service Portal. Examples would be ALL of the padding classes (i.e. p-t-sm), and the medium margin classes (i.e. m-t-md).

    Do you know which ones we should expect to run into issues?

  2. Brian, you are correct. It looks like many of the original utility classes were removed at some point. My bad for not double checking. I’ve updated the document using the actual utility stylesheet in Istanbul.

  3. Hi Nathan,
    I need to know how to make something visible in tablet view and not in mobile view. Because when we use hidden-xs it hides in both mobile and tablet view. which class should we need to use?
