Text Ids add a span with an id around the text you specify it so you can reference a range of text later.
For example, let’s say you are displaying information to your visitor in a text field and that information will change.
Name: John Smith
Then you can add text to find and an id to use around it.
<div id="text1"> <span>Name: John Smith</span> </div>
<div id="text1"> <span>Name: <span id="username">John Smith</span></span> </div>
Separate each text id name and value pair with a semicolon.
Text IDs are case sensitive.
