This article mainly introduces "what is the HTML size unit". In the daily operation, I believe that many people have doubts about what the HTML size unit is. The editor consulted all kinds of data and sorted out a simple and easy-to-use method of operation. I hope it will be helpful for you to answer the question of "what is the HTML size unit?" Next, please follow the editor to study!

The unit used to describe size is the unit of size.

For example, the size of the description text, the height of the description lines, the width of the description div, the spacing between lines, and so on.

Different elements may have different units of size, such as pixel / em/ percentage for font size, pixel / percentage for div width, and so on.

Use pixels to set the text size, as follows:

Font-size: 30px

Use em to set the font size as follows:

Font-size: 3.75em

Em units are equivalent to multiples, 1em is equal to the current font size, and the default text size for browsers is 16 pixels, so the default size for 1em is 16 pixels, and 3.75em is 60 pixels.

Note: the so-called current font size refers to the font size of the current element, if the current element does not define the font size, it is equal to the font size of the parent element of the current element.

The so-called parent element refers to the element above the nesting relationship of the current element.

For example, introduction

You can calculate that the font size of the element div is 60px.

From this, it can be concluded that the pixel is absolute and is not affected by the superior-subordinate relationship, while the em is affected by the superior-subordinate relationship and should be used according to the specific situation.

Exercise:

Add the font-size attribute to the style of body, then change the font-size attribute of div to em units, and adjust the value in two ways.
