=head1 NAME

Selenium::Remote::WebElement - Representation of an HTML Element used by Selenium Remote Driver

=cut

=head1 DESCRIPTION

Selenium Webdriver represents all the HTML elements as WebElement. This module
provides a mechanism to represent them as objects & perform various actions on
the related elements. This module should not be instantiated directly by the end
user. Selenium::Remote::Driver instantiates this module when required. Typically,
the find_element method in Selenium::Remote::Driver returns this object on which
various element related operations can be carried out.
