This may be a proprietary, non-standard element, but since Opera has implemented it, they really should get it right.
marquee speeds are incorrectly implemented. If truespeed is not specified, scrolldelay should be limited to a minimum value of 60. Opera gets this wrong as shown in examples 3, 5 and 7 below which should have the same scroll speed as examples 1 and 2.
Opera also appears to set it's own minimum value of 40 to scrolldelay no matter the setting of truespeed, which results in example 8 not scrolling fast enough.
scrolldelay=60 scrolldelay=60 truespeed scrolldelay=41 scrolldelay=40 scrolldelay=1 |
This is intended to show that Opera treats scrolldelay values 1 through 40 the same, but 41 is slightly different. All five lines should be scrolling at the same speed as the first line. | |
