WebTextEditor provides built-in professional styles for working with editor in design view. For instances, each paragraph and headings will be properly formatted to make the document more readable.
In addition, WebTextEditor also provides flexibility for developers to add their own CSS files into the editor by adding each CSS file in the CssFiles collection. See an example in the following.
<ISWebTextEditor:WebTextEditor ID="WebTextEditor1" runat="server" Height="500px" Width="700px">
<RootTextEditor Content="<h2>Intersoft WebAqua . . .">
<CssFiles>
<ISWebTextEditor:WebTextEditorCssFile FilePath="Css/CustomEditorStyle.css" />
</CssFiles>
</RootTextEditor>
</ISWebTextEditor:WebTextEditor>
