How to change the size of a sign

I want to change the sign ^ to be wider and bigger when written over a letter like this: ô

How do I go on about doing this?

Answer

To do this you would need to change to a font that will represent the character like that. You can include non-websafe font in a page https://www.w3schools.com/css/css3_fonts.asp

The other option would be to use a javascript latex renderer and use that to specify that you want a wider hat.
