FWIW, MSIE 10 and Opera 12 also render "incorrectly".

Comment 2

[Boris Zbarsky [:bzbarsky]]

The page uses absolute positioning on the text bits, using pixel offsets.  That assumes things about font metrics that are just not going to be true across font rasterizers, operating systems, etc.

Case in point, all of Opera, Safari, Chrome, and Firefox show overlap on that testcase over here, and all have slightly different amounts of it.

if there is a valid function that returns position and contents valid it must be validated by naturally browser that is usual and normal procedure. 

In the example, if inserting line break in the same code above, it will display the contents properly.  

<div style="position: absolute; top: 2px; left: 0px; width:423px; font:16pt Times New Roman; color: #000080">Os&nbsp;partidos&nbsp;da&nbsp;classe&nbsp;dominante&nbsp;eram&nbsp;os&nbsp;Saduceus&nbsp;</div>
<div style="position: absolute; top: 25px; left: 0px; width:257px; font:16pt Times New Roman; color: #000080">(principalmente&nbsp;na&nbsp;Judéia)&nbsp;e&nbsp;os</div>

Many developers, report writers use building the argument by absolute position.

"following the path of the science of mathematics, the order of the factors can not change the result"

I have no idea what you're trying to say there.  Please feel free to write in Portuguese and I'll find someone to translate if that would be easier.

Where did you insert the line break, exactly?  I see no difference in the layout of the code from comment 3 no matter whether I put it on one line or two.

Yes, and they're producing buggy pages that break on any computer that's not theirs.  So the ones that want to stay in the business stop doing that...
