CSS Modal Box without Javascript or Images

Using CSS3 tech­niques a modal box can be cre­ated with­out JavaScript or images. With a bit of ani­ma­tion, tran­si­tion and trans­form, it can be made that lit­tle bit more special. Here we have CSS Modal by Paul Hayes.

The modal animation is hardware accelerated on Safari and iOS, which gives notable performance improvements. The animations are available in Chrome but will feel more sluggish. Firefox will see the opacity transition but not the bounce or minimise animation as it doesn’t yet support @keyframe.

However, it won’t work in IE8 and below, there’s no pointer-event sup­port and opac­ity is poorly imple­mented. IE9 sup­ports :tar­get but no pointer-events. Some IE spe­cific styles could eas­ily switch the opac­ity tog­gle to a dis­play or vis­i­bil­ity one.
