+* $content_width is a global variable used by WordPress for max image upload sizes and media embeds (in pixels)
+*
+* Example: If the content area is 640px wide, set $content_width = 620; so images and videos will not overflow.
+*
+* Default: 940px is the default Bootstrap container width.
+*
+* This is not required or used by Roots.
