# Helper classes
This is a list of all the typography helper classes available. They are used by the [Span](/uilib/elements/span) and [Paragraph](/uilib/elements/paragraph) components, but can also be used on their own.
For visual examples, see the [Paragraph demos](/uilib/elements/paragraph/#demos).
For details on sizes and weights, see the [Font weights](/uilib/typography/font-weight/), [Font size](/uilib/typography/font-size/) and [Line Height](/uilib/typography/line-height/) documentation.
