HTML Output

Styles for Telerik controls are defined using Cascading Style Sheet (CSS) syntax. Each style consists of a selector that identifies an HTML element to be styled, and property/value pairs that describe each of the style specifics, e.g. color, padding, margins, etc. For example, the .RadLightBox_Default style defines the default color and font styles for the entire control:

    color: #333;
    font: 12px "Segoe UI",Arial,Helvetica,sans-serif;
