I am creating a child theme and changing some of the HTML code in the php files. For the widgets in the side bar, I want to change <div class="widget-title"> to <h2 class="widget-title"> as it is a heading. Screen readers use the H tags to help navigate.
So far, I tried changing inline all the sidebars, core/functions.php, created a copy for the child them and made changes there...
