Remarks
Use FindElement... methods to find an element within a template. You can search for elements that need to be modified by their tags, CSS classes, and IDs. The FindElementsByTag and FindElementsByClass methods return a list of all matching elements, whereas the FindElementById method returns a single element.
When an element that you want to modify is located, use the Style.SetProperty method that takes two parameters: the attribute name and new attribute value (if no attribute with such name was found, it is added to the CSS style).
The code sample below illustrates how to locate a <div> element with the specific ID, and change its background color.
void OnCustomizeTemplate(object sender, DevExpress.Utils.Html.DxHtmlElementEventArgs e) {
var topDivElement = e.Element.FindElementById("parentDiv");
topDivElement.Style.SetProperty("background-color", "Orange");
