CSS text-size-adjust Property
Experimental: This is an experimental technology.
The text-size-adjust CSS property controls the text inflation algorithm used on some smartphones and tablets. Other browsers will ignore this property.
Because many websites have not been developed with small devices in mind, mobile browsers differ from desktop browsers in the way they render web pages. Instead of laying out pages at the width of the device screen, they lay them out using a viewport that is much wider, usually 800 or 1000 pixels. To map the extra-wide layout back to the original device size, they either show only part of the whole render or scale the viewport down to fit.
Since text that has been scaled down to fit a mobile screen may be very small, many mobile browsers apply a text inflation algorithm to enlarge the text to make it more readable. When an element containing text uses 100% of the screen's width, the algorithm increases its text size, but without modifying the layout. The text-size-adjust property allows web authors to disable or modify this behavior, as web pages designed with small screens in mind do not need it.
The following table describes the values of this property:
|Disables the browser's inflation algorithm.
|Enables the browser's inflation algorithm. This value is used to cancel a none value previously set with CSS.
|Enables the browser's inflation algorithm, specifying a percentage value with which to increase the font size.
|Sets this property to its default value.
|If specified, the associated element takes the computed value of its parent element animation-delay property.
|Reverts the cascaded value of the property from its current value to the value the property
|Rollback styles to the ones specified in previous cascade layers.
|Resets a property to its inherited value if the property naturally inherits from its parent, and to its initial value if not.
