HTML, CSS: matching square root characters

Question

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

& Radic; & MACR; & MACR; & MACR; & MACR; & MACR; & MACR; & Phi; & Midot; (2? & Minus
;? ) & Thinsp; & EPRS; & EnSP; & thinsp; & uarr; & EPRS; & LARR; & EPRS; & LARR; & EnSP; & thinsp; & LARR;

How can I move my expression to the left, under the symbols ¯, so that they overlap each other? Note: It should work on every font size.

Thank!

_{(My current code, thanks to Matthew Jones ^{(+ 1)} fortext-decoration: overline , there is not enough size scaling and proper positioning of the add-in. This is why I edited this question because it ¯matches the size and position in the Georgia font.)}

Answer 1

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 mathdefines a font-family: Georgiaand font-size)

It works on any font! :-)

You can set CSS for the text to be displayed below the panel as

text-decoration:overline

: , (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>

, ...

Answer 3

you can easily place the characters under the root in a separate run, and then draw it using the frame on top. But you may have to increase the font size √so that it lines up.
