CSS Property: font-size-adjust

Adjusts the font size to be in relation to lowercase letters.

This can be helpful for legibility of small text, especially when the font in use is unpredictable (such as being a second choice font in a font-family list). When more than one font is being used it also allows the fonts to be aligned vertically in respect to the lowercase rather than uppercase letters.

Possible Values

ValueNoteExample
[number]A multiplier of the font-size value.0.5
none
inherit
initial
unset

Example


p {
    font-size: 16px;
    font-size-adjust: 0.5;
}
/* Suggests lowercase letters of paragraph text should be eight pixels high and other character sizes should be in relation to them. */
