Web Designer IDs As Selector

Within one page, all Web Designer objects have a unique ID. Examples of these IDs include:

•SaveButton, CheckButton, NewButton, and DeleteButton button controls. "SaveButton" is the unique ID, ButtonControl is the class of the SaveButton control.

•A "TitleLabel" LabelControl.

•A "SearchGroup" ContainerControl.

•A "SearchButton" ButtonControl.

Just as with classes, these IDs are generated into the client HTML documents. Here is an example:

<div id="TitleLabel" class="TitleLabelControl">Tours</div>

By using the (HTML) ID attribute as a selector, you can set style properties for each individual HTML element. You can attach a style sheet rule to a specific HTML element by preceding the ID name with the "#" symbol. For example, this style sheet rule specifies that all HTML elements with ID "Prompt" are in italics:

#Prompt{
   font-style: italic;
}
