Make Compact Grid Elements Smaller

Environment

Product

Grid for Blazor

Description

I am using the Grid sizing feature and my Grid is a Compact Grid. I want to reduce the size of all elements in the Grid. How can I:

• Change the size of all icons in the Grid?
• Set smaller font size to all elements in the Grid?

Solution

1. Set the Grid Class parameter to a custom CSS class. This allows you to target specific Grid instances.
2. Use the defined class to override the theme styles of the desired elements in the Grid.
