How to use the css box-flex attribute?
Function: Specifies whether the child elements of the box can expand or contract their size.
Syntax:
box-flex: value;
Description: The scalable row of value elements. Flexibility is relative, for example, a child element with a box-flex of 2 is twice as flexible as a child element with a box-flex of 1.
Note: Scalable elements can shrink or expand as the box shrinks or expands. Whenever there is extra space in the box, the scalable element expands to fill that space. No browser currently supports the box-flex attribute. Firefox supports an alternative -moz-box-flex property. Safari, Opera, and Chrome support the alternative -webkit-box-flex attribute.
