In particular, if flex sizing is being used for a major content area of a document,

it is better to set an explicit font-relative minimum width such as <a class=css data-link-type=propdesc href=http://www.w3.org/TR/CSS21/visudet.html#propdef-min-width title=min-width>min-width: 12em</a>.
3461-
A content-based minimum width could result in a large table or large image
3462-
stretching the size of the entire content area into an overflow zone,
3463-
and thereby making lines of text gratuitously long and hard to read.
3464-
3465-
<p>

Note also, when content-based sizing is used on an item with large amounts of content,
3467-
the layout engine must traverse all of this content before finding its minimum size,
3468-
whereas if the author sets an explicit minimum, this is not necessary.
