Hi CanIUse team,

I’m working on a fraction library that utilizes MathML, and I’ve encountered an issue with the bevelled="true" attribute, which is used to render fractions diagonally (e.g., ??? instead of 5/7). While testing, I noticed inconsistent support across browsers, but I couldn’t find any definitive data on the percentage of browsers that support this feature.

Could you please consider adding support data for the bevelled="true" attribute in MathML to caniuse.com? This would help developers like me understand the compatibility of this feature across different browsers and make informed decisions when implementing MathML-based solutions.

Here’s an example of how the attribute is used:

<math>
  <mfrac bevelled="true">
    <mn>5</mn>
    <mn>7</mn>
  </mfrac>
</math>

This renders the fraction 5/7 diagonally when supported. However, it seems many browsers either don’t support it or render it as stack.

Why is this important?

• MathML is widely used in educational tools, scientific applications, and math-related libraries.
• The bevelled attribute is a key feature for rendering fractions in a more visually appealing and mathematically accurate way.
• Without clear compatibility data, developers may avoid using this feature, limiting its adoption and usefulness.

Suggested Approach:

• Add a new entry for bevelled="true" in MathML under the MathML section on caniuse.com.
• Include support data for major browsers (Chrome, Firefox, Safari, Edge, etc.) and their versions.
• Highlight any known inconsistencies or rendering issues.

Thank you for considering this request! Your platform is an invaluable resource for web developers, and adding this data would greatly benefit the community.

Best regards,
Wasiu
