I am into Accessibility testing. In my case we have Two headings
<h1 class="CssPropertywithSmallFontSize">Heading One</h1>
<h2 class="CssPropertywithBiggerFontSize">Heading Two</h2>
Visually H1 looks smaller than H2 due to the CSS property added to it. Is such a scenario acceptable based on WCAG 2.0 ?
