Details

Using both 1.1 (20020826) for Mandrake Linux 9.0 and 2002112112 OS/2 trunk. Neither system has Verdana installed. Both have Helvetica installed. Systems are both set to default font size 16 px. Subject URL css is set to display body text at .8 em using font-family: Verdana, Helvetica, Arial, sans-serif;. Ctrl++ sets body text to the neighborhood of .90-.93 em. Ctrl++ a second time skips over 1.0 em to the neighborhood of 1.10-1.15 em. Thus, there is no simple way to get the page's body text to the user's choice of font size. Whatever the algorythm for determining the smaller/larger increment, 1.0 em should not be skipped over. I've seen many other pages exhibiting this behavior, (e.g. http://www.microsoft.com/) but I think the subject matter of this URL serves as an ironic emphasis of the need for this. I read bug 31961 with great interest. That should very useful if it ever comes to pass, but I don't think it would obviate the need for this. I also read all the way through bug 37940, and think it should be reopened or another bug filed to make the fixed percentages reflect common situations better. e.g., on the subject URL, 120% results in approximately .90-.93 em, while 150% results in approximately 1.10-1.15 em, both just like using the keyboard shortcuts.
So the request is that Ctrl-+ and Ctrl-- change the text size such that the "main body text" does not shoot through the user's default font size. Now how do we decide which text on the page is the "main body text" exactly?
BZ: We don't need to know "main body text" size. We only need to query the value of 1em in prefs, and not pass that size without first stopping on that size. One reason for the enhancement request is the coarseness of the increment. A whole bunch of common font faces jump to bold at the first common stop beyond 1em, somewhere around 1.1em-1.15em. I keep hitting pages where the whole .92em-1.08em range is skipped over, and getting the size at least to 1em bolds everything.
> and not pass that size without first stopping on that size Not pass that size for _what_ exactly? <body style="font-size: 10px"> This is text <p style="font-size: 12px">More text</p> <p style="font-size: 8px">More text</p> </body> What is your expected behavior on that page?
That example is easy. The median size is 10px. If 10px is smaller than 1em, then apply the plateau to the median size on increment. If 10px is larger than 1em, then apply the plateau to the median size on decrement.
My point is that calculating the "median size" is _hard_. And very expensive. And likely to fail, imo (eg on many pages the median size will end up the size of the link bars on the sides, not the size of what people care to read). The point is, suggest an actual useful way to do this. ;)
I don't know how to make it easy or inexpensive, but maybe I have an alternative that would produce the same effect: How about changing the hotkey increment/decrement from whatever it is now, to one pixel, and adding two more increments in the view->zoom menu in between 100% and the two changes adjacent? Fonts sizes now are converted to integer pixel values for rendering, aren't they? 100% -> 120% is just too coarse to be able to land on 1em, especially if the two following increments land on 150% and 200%. But, by changing the increment to a pixel, surely it could.
Summary: smaller/larger Ctrl++/Ctrl+- should not skip over default size (1.0 em) - text zoom → text zoom should not skip zoom percent that makes page text match user's chosen default size
Summary: text zoom should not skip zoom percent that makes page text match user's chosen default size → text zoom should not skip percent that makes page text match default font size

Mozilla > Preference > Advanced > Mouse Wheel > Make the text larger or smaller I find that using the mouse wheel provides a finer text-size increment than Ctrl+ and Ctrl-. Using the wheel is a significant improvment. Only problem is that when the wheel is selected for this function, it can't be used to scroll anywhere in Mozilla. Obviously, that includes scrolling through webpages and emails. Also, with a few hundred folders in my email accounts to scroll through, it's a problem having the wheel disabled for scrolling through all those folders. Thanks, -Neil-
