Let me make a sample, I will change the h2 tag to a div tag:
<div class="t3-off-canvas-header-title">Sidebar</div>
Then in the file: /templates/ja_autoshop/css/custom.css (Create this file if it doesn't exist), add this custom css:
.t3-off-canvas .t3-off-canvas-header .t3-off-canvas-header-title {
color: #ffffff;
margin: 0;
line-height: 40px;
font-size: 12px;
font-weight: bold;
text-transform: uppercase;
}
This custom code will help to keep the same style as when using h2 tag.
