In css, the line-height attribute is used to set the amount of space for multiline elements, such as text. For block-level elements, it specifies the minimum height of the element row box. For non-substituted inline elements, it is used to calculate the height of the rowbox.

line-height syntax

/*Keywordvalue*/

line-height:normal;

/*Unitlessvalues:usethisnumbermultiplied

bytheelement'sfontsize*/

line-height:3.5;

/*values*/

line-height:3em;

/*values*/

line-height:34%;

/*Globalvalues*/

line-height:inherit;

line-height:initial;

line-height:unset;

line-height value

Normal depends on the client. Desktop browsers (including Firefox) use a default value of about 1.2, depending on the font-family of the element.

The applied value of this attribute is this unitless number multiplied by the font size of the element. The calculated value is the same as the specified value. In most cases, this is the recommended way to set line-height and does not produce indeterminate results when inheriting.

Specifies the height used to calculate the linebox. See for possible units. Values in em may produce inconclusive results.

Relates to the font size of the element itself. The calculated value is the font size calculated by multiplying the given percentage value by the element. Percentage values can lead to inconclusive results.

After testing, in the above several forms, values with units will be inherited by sub-elements, and only values without units (such as 1.2) or normal will not be inherited.

Test Code:

div{

font-size:14px;

}

.p1{

line-height:21px;

}

.p2{

line-height:1.5;

}

.p3{

line-height:150%;

}

.p4{

line-height:1.5em;

}

.p5{

line-height:normal;

}

h2{

width:8em;

overflow-wrap:break-word;

font-size:28px;

}
