Locator.highlight() method highlight all the matching elements on the screen.
Example

Find the below working application.

<h1>Highlight matching content demo</h1>
<p> The Java Programming Language solves all the above problems. The Java programming language platform
provides a <span class="impt">portable, interpreted, high-performance, simple, object-oriented programming</span> language and supporting
run-time environment.
<br /><br />
Java Design and architecture decisions drew from a variety of languages such as <span class="impt"> Eiffel, SmallTalk, Objective C,
and Cedar/Mesa</span>. Closely observed the problems in the other languages like platform dependent, Pointers
complexity, Manual garbage de allocation etc., Java removes the basic problems in other languages.
