+# Layout Builder Styles
 
 Layout Builder Styles allows site builders to select from a list of styles to
 apply to layout builder blocks and layout builder sections. A "style" is just
 a representation of one or more CSS classes that will be applied. Additionally,
 for blocks, a block template suggestion is added for the selected style.
