# Limitations *Text Animations for UI Toolkit* use visual elements for each letter. Visual Elements are created with performance hints, so UI Toolkit can optimize the elements in the background, making the animations very fast once all elements are created. Because each letter is a UI Toolkit `Label` we are limited to anything supported by visual elements, which means we are limited to animating the following properties: * Vertical and Horizontal Offset * Color * Opacity / Alpha * Size * Rotation --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
