[i]The "ex" measurement is relational to line height in which a set font size resides. This in laymans term is the "control of line height".[/i]

Using the [i]search[/i] credentials of " What is the purpose of ex measurement unit in CSS? " the [i]search[/i] yielded this (along with a multitude of others) [url=https://www.w3.org/TR/css3-values/#ex]Technically Speaking at w3schools[/url].

    Sometimes the "edit" would be a god send ...

    [i]Technically Speaking at w3schools[/i] was meant to read: in your schooling (teaching yourself new things) visit [url=https://www.w3.org/]w3.org (The World Wide Web Consortium (W3C))[/url].

    The ex unit is rarely used. Its purpose is to express sizes that must be related to the x-height of a current font.

    [code=html]
    <!DOCTYPE html>
    <html>
    <head>
    <style>
    div {
    font-size: 40px;
    border: 1px solid black;
    }

    span {
    font-size: 1ex;
    }
    </style>
    </head>
    <body>

    <div>The font-size of the div element is set to 40px. </br><span>The span element inside the div element has a font-size of 1ex</span>.</div>

    </body>
    </html>
    [/code]

    Thanks.
