About html & html5

I'll also add that I wanted the vignette constant, which is why I chose position:fixed. You can use position:absolute if you want it at the top and bottom of the page rather than the top and bottom of the window. But of course your way is simple. I just wanted to do it without additional HTML markup.

It scrolls really slow on Chrome 29.

 

No, because it won't scroll with the window in anything but FF -- and as usual FF is as wrong on that behavior as IE used to be at just about everything.

And Opera 12, Opera 15... I'm a little shocked FF doesn't choke on it since historically it's worse.

There's a reason for that too -- generated content creates a COMPLETE reflow of the entire page on every scroll; This is why as cool as generated content can be and how much it can 'simplify' markup, it still needs to be used with an eyedropper.

Kind of like how FF sucks at linear gradient if you let it go 100% x 100% -- which is why if you use linear gradient across just one dimension, you are best off setting a repeat on one axis and using background-size to make that axis 1px wide. No joke -- it also lowers the memory use because linear-gradient generates the full size as a image in memory (which is REALLY ****tarded when it's not diagonal) -- Though it's been better as of FF 21.

Now if they could just get off their asses and fix the fifteen year old bugs in Gecko's HTML4/CSS2 implementation that are VERY quickly turning Gecko browsers into the new IE6!

 

Oh, and position:fixed is ALSO prone to making rendering on scroll be a bloated slow PITA -- just like dithered transparency backgrounds from the peak of the "myspace" era did.

One of the reasons I avoid position:fixed in the first place.

 

I have to confess I STILL don't know what you're talking about here. On my system with those settings, nothing breaks at all. Zoom 100%, text to any setting is fine.

Sometimes I wonder if you have a virus, 'cause I'm just not seeing these issues.

 

Weird. Doesn't scroll slow for me, although I find Firefox slightly smoother.

For all the Chrome fanbois out there, though, most people are unaware that actually Chrome has serious issues—poor page load reliability and all sorts of other stuff. Maybe you're getting some of that; I dunno.

For fun, here's a recent evaluation of the major browsers: http://www.tomshardware.com/reviews/chrome-27-firefox-21-opera-next,3534.html

 

HTML5 is the latest version of HTML. There are some addition elements there which made coding little easier.
<canvas>
<audio>
<video>
<source>
<embed>
<track>
<datalist>
<keygen>
<output> are some examples of HTML5 new elements.
