Hi,

I am very disappointed by the way that Mozilla Firefox support tag. Please, try to display the code below with Firefox then Safari : you will get why I mention that Firefox has a wrong <del> tag support :

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    
    <style>
h1 {
font: 3.4em/4 "Helvetica Neue";
font-weight: 100;
font-style: italic;
}
    </style>
    
</head>
<body>

 <h1>My <del>ex</del>Title</h1>

</body>
</html>

Can you attach a screenshot to show the difference?

Use a compressed image type like PNG or JPG to save the screenshot.

There are 2 screenshots. The first one is Firefox and second one is Safari.

So Firefox displays the strike through thicker and at a higher position.

Does this happen with all fonts?

I'm not having this Helvetica Neue font, but Firefox shows the strike through at about the middle of the characters for me.

I can only compare Firefox and Chrome. Seems that both place the line through the center of a lower case x (half of the x-height) when the font size is a bit larger but where they vary, Chrome aims higher and Firefox aims lower.

Not sure there is any applicable standard for exactly where a line-through is drawn.

Note: You can change the font-family in the Fiddle and save as a new version if you like.

Thank you jscher2000! As you said I don't think there is any applicable standard for this issue.
