Fixed pixel based font sizes and parent elements

What are fixed pixel based font sizes and parent elements? Thx in advance

If a font is pixel based it simply means you are using pixels as a unit of measurement. Same way you would measure something in inches, cm, feet etc. Its also worth mentioning that besides pixels there are ems, rems and points which are used in place of pixels. Also there are percentages but i would not use them on fonts.

Parent element are those elements that can nest other elements e.g the <body> element is the parent element of all the elements inside it. also the <ol> is the parent element of <li>. Also there is the <form> element.

An example of a "fixed pixel-based font size" would be "16px". A setting like this is not related to anything else and would always be the same size. This is different from a relative size unit like "em", where the actual size shown will be based on other settings.

A "parent" element is one that contains the element of concern. For example, in this code:

<div>
    <p>Here is a paragraph.</p>
</div>

The "div" shown above is the parent element of the paragraph ("p").
