Is there a way in HTML4 and/or CSS to do the following, but then correctly:

√¯¯¯¯¯¯φ·(2π−γ)
    ↑ ← ←  ←

How can I move my expression to the left, under the ¯ symbols, such that they overlap eachother? Note: it should work on every font-size.

Thanks!

(My current code, thank you Matthew Jones(+1) for the text-decoration: overline, lacks the scaling of sizes and correctly positioning the overline. That's why I edited this question, as ¯ does match in size & position in the Georgia font.)

  • Tip: Start using Latex. As soon as you have fractions etc. under the root symbol, it gets even harder. – Avatar Apr 22 '20 at 07:06

You could set the CSS for the text that should appear under the overbar as

text-decoration:overline

EDIT: This comes pretty darn close to what you want (Chrome 4.1.249):

<div style="font-family: Georgia; font-size: 200%">
    <span style="vertical-align: -15%;">&radic;</span>
    <span style="text-decoration: overline; vertical-align:-20%;">&nbsp;x&nbsp;+&nbsp;1&nbsp;</span>
</div>

Unfortunately there does not appear to be a way to modify the thickness of the overline itself...

  • I just tested that on the above example using Firebug and it works *perfectly*!. – EAMann May 18 '10 at 20:44
  • I see (though the enter after the span adds horizontal space, I presume you added it because of formatting on StackOverflow). Though, lowering the expression wasn't my goal, just lowering the bar, the text is at a good position. Thanks for helping me. – Pindatjuh May 18 '10 at 20:59

    This works perfectly for me if there is no whitespace between the first end span tag and the next start span tag. `` http://jsbin.com/utolo You could also use a `border-top` declaration to try and match the thickness and it looks pretty good: http://jsbin.com/utolo/2 – ghoppe May 18 '10 at 21:18
  • Messed with the vertical-align (setting it to -25%) to make it line up better. Score! http://jsbin.com/utolo/3 – ghoppe May 18 '10 at 21:24
  • The problem is that when the size is smaller, they don't match up. As I would like to use this as a "container", how big or small it will be, it should always match the root's tail. (For instance, the size will be smaller inside a division than "stand-alone".) – Pindatjuh May 18 '10 at 21:24

    @Pindatjuh I would make two styles then, large and small (for division)… or more. I don't think it's going to be feasible to code css that will perfectly match the font metrics for the √ symbol regardless of size. http://jsbin.com/utolo/4 – ghoppe May 18 '10 at 21:34

you miight be able to put the characters under the root in a seperate span then style it with a border on top. But you'll probably have to increase the font-size of the &radic; to make it line up.

  • Actually `border-top` works perfectly! Check out this fiddle to compare it to `text-decoration:overline` http://jsfiddle.net/qDZNB/ – chowey Aug 30 '13 at 05:00

The following works exactly as I wanted it:

<div class="math">
    &radic;<span>&macr;&macr;&macr;&macr;</span><span style="margin-left: -2.39em; vertical-align: 0.1em;">x + 1</span>
</div>

(Where math defines a font-family: Georgia and font-size)

This works on any font-size! :-)
