Creating a design using HTML and CSS that involves an overbar matching square root symbol

Is it possible to achieve the following layout using HTML4 and/or CSS in a correct manner?

√¯¯¯¯¯¯φ·(2π−γ)
    ↑ ← ←  ←

How can I align my expression to the left, below the overlapping ¯ symbols across different font sizes? Note: this should be consistent regardless of the font size.

Thank you!

(My current code, revised with help from Matthew Jones(+1) regarding the use of text-decoration: overline, lacks the ability to scale font sizes and position the overline correctly. This is why I have updated this question, as ¯ matches the size and alignment in the Georgia font.)

Answer №1

If you want to style the text under the overbar, you can use CSS like this:

text-decoration:overline

UPDATE: This code comes close to achieving the desired effect (tested on 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, it seems that adjusting the thickness of the overline itself is not possible...

Answer №2

One possible solution could be to place the characters below the root in a separate span and then customize it with a top border. However, you may need to adjust the font size of the &radic; symbol to ensure proper alignment.

Answer №3

<math xmlns="http://www.w3.org/1998/Math/MathML">
    <msqrt>
        <mrow>φ(2π−γ)</mrow>
    </msqrt>
</math>

Answer №4

I finally found a solution that works perfectly for what I needed:

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

(In this case, the math class uses font-family: Georgia and font-size)

This solution is versatile and works well with any font size! :-)
