Do I get the approval to modify the {{intmath}} template for text style HTML+CSS only (using the above tested code)? I don't think Wikipedia wants the display style HTML+CSS option, since LaTeX works nicely for display style. — Tentacles^{✉ mailto:Tentacles} 20:53, 13 March 2016 (UTC)

The purpose of this template is to serve as alternative to using the <math>...</math> tag. There are a number of problems with the math tag which depend on the options used. There are three main different modes available, in particular nologged in users use the rather ugly PNG output. The following shows what an IP will see

note the aliasing problems and the dropped baseline with the <math>. Until the math rendering is sorted out inline <math>...</math> will still look bad to some users, which is why editors still want to use css for some inline equations.--Salix alba (talk): 21:36, 13 March 2016 (UTC)

I totally know about all the issues of [inline] text style LaTeX PNG's, that's why I'm working hard on improving the presentation of the [inline] text style HTML+CSS rendering of the integrals. The reason why I have the LaTeX renderings above is to compare my HTML+CSS renderings with the LaTeX renderings to fine tune my CSS code, so that the HTML+CSS renderings look as good as LaTeX renderings. — Tentacles^{✉ mailto:Tentacles} 22:23, 13 March 2016 (UTC)

Suggestion of new template code

Here is the (tweaked and/or optimized for use inside the {{math}} and {{bigmath}} templates) latest (April 09, 2016) code that I propose. (∫ is treated separately because it renders in a different font, which also have a higher vertical alignment.)

— Tentacles^{✉ mailto:Tentacles} 22:23, 13 March 2016 (UTC)

I would suggest putting the code into Template:Intmath/sandbox and creating some testcases in Template:Intmath/testcases. If you do that we can then examine the results and compare it with current version. See Wikipedia:Template sandbox and test cases for instructions on how to format there. Once everyone is ok with the changes we can then make things go live.--Salix alba (talk): 20:40, 15 March 2016 (UTC)

I've created the above sandbox and testcases. On my browsers and fonts the, iint, iiint oint, oiint varients all look better. There are problems with the int versions as the sub and superscripts overlap the integral sign. It might need a bit more rightmargin space, or it could be rendered not in italic which also seems to cure the overlap problem.--Salix alba (talk): 20:19, 20 March 2016 (UTC)

The code is tweaked and/or optimized for use inside the {{math}} template. — Tentacles^{✉ mailto:Tentacles} 17:55, 21 March 2016 (UTC)

In Firefox 37.0.2 and IE 11 (Windows), the int version worked fine for me (the sub and superscripts did not overlap the integral sign). — Tentacles^{Talk or ✉ mailto:Tentacles} 21:59, 21 March 2016 (UTC)

Also, it bugs me somehow that int is not italic while all the others are (it's not consistent). — Tentacles^{Talk or ✉ mailto:Tentacles} 21:59, 21 March 2016 (UTC)

I rotated the int symbol with a CSS transform (does Wikipedia approve using CSS transforms?) but there is an issue of too much line height then. (Now, the default option gives a non-rotated int as a fallback.) — Tentacles^{Talk or ✉ mailto:Tentacles} 01:45, 22 March 2016 (UTC)

I can't yet get int_italic to work properly (using CSS transform: rotate or transform: skewX) on both browsers... any hint would be helpful! (Unless we can get int_italic to work properly, int will have to default to int_normal.)

• Firefox 37.0.2 (Windows)
• IE 11 (Windows)

— Tentacles^{Talk or ✉ mailto:Tentacles} 19:51, 22 March 2016 (UTC)

CSS transform: rotate or transform: skewX somehow work on IE 11 (it actually rotates and skews) but there seems to be an issue with transform-origin: because the integral symbol goes up by a huge amount. Any help from a CSS transform expert would be great! — Tentacles^{Talk or ✉ mailto:Tentacles} 20:21, 22 March 2016 (UTC)

Whatever I try doesn't make any difference in IE 11!? How could that be? I keep purging the server cache to make sure. — Tentacles^{Talk or ✉ mailto:Tentacles} 21:09, 22 March 2016 (UTC)

I resolved the issue. The sandbox code now appears to work well in Windows with Firefox 37.0 and IE 11. Do you have any objection with the code (is it OK that I use a CSS transform to rotate the integral symbol)? Do you consider the code ready to be made live? — Tentacles^{Talk or ✉ mailto:Tentacles} 20:31, 24 March 2016 (UTC)

The italic int looks OK in Chrome/Firefox on my Macbook machine, there is still overlap on first upright testcase. A big thing which should be checked is mobile, as about a quarter of view are now from mobile.

For whats its worth the reported fonts are a combination of Helvatica and "Apple Symbols". I've a few nice maths fonts on my systems LatinModernMath-Regular, DejaVu Sans.--Salix alba (talk): 21:30, 24 March 2016 (UTC)

Do you consider the {{intmath/sandbox}} and {{intmath/int/sandbox}} code ready to be made live? I tested the code in Firefox 37.0.2 and IE 11 (both on Windows) and everything seems OK. If I get the approval I'll make it live. — Tentacles^{Talk or ✉ mailto:Tentacles} 20:16, 30 March 2016 (UTC)

Look at {{intmath/testcases#Text style inline formulae}}: Line spacing in lorem ipsum text is undisturbed. (There is no more excess of space above.) I will make the code live. Any objections? — Tentacles^{Talk or ✉ mailto:Tentacles} 23:44, 9 April 2016 (UTC)

Please don't. There is no consensus for this change. Also, I see nothing wrong with the current code, and there are issues with yours. For instance, the line-height might not be affected, but the oint symbols now overlaps the over- and underlying text instead. I also see double-italizised symbols due to the transform-rotate. I already tried explaining that micro-tweaking, while it may look good on your own system, will not work as intended on other systems due to inconsistencies in font metrics, so the generic code is the best solution for now. -- [[User:Edokter]] {{talk}} 07:57, 10 April 2016 (UTC)

OK, I won't. Is it the case that everything that could have been tried to improve the typesetting of HTML+CSS math has already been attempted? If that's the case, it means that we essentially have to live with lots of lame HTML+CSS typesetting and that attempts to improve things are quite futile and a waste of one's time. (The fact that there is not even a consensus to use the {{math}} and {{bigmath}} templates when typesetting math in HTML+CSS only makes the typesetting lamer.) I tested on Firefox 37.0 and IE 11 (both on Windows) and the Gauss's Law integral oiint symbol does not overlap the over- and underlying text and the line spacings are undisturbed. I also do not see double-italizised symbols. On which device and/or system and/or browser do you see the issues that you mention? — Tentacles^{Talk or ✉ mailto:Tentacles} 18:24, 10 April 2016 (UTC)

Chrome 49 on Windows XP, but also Windows 7. The fact there is no consensus to use the math templates does not mean it is ignored. I devised {{math}} back in the days when TeX stil used HTML for simple formulae, and spent quite some time fine-tuning it to suit the widest array of devices. Your approach may look fine on your system, but does not account for any ohter platforms where ohter default fonts may display different; the {{unicode}} template does nothing outside XP, and different Windows versions have different built-in support for oint characters, using different substituted fonts alltogether. Sorry for all that work you put in. -- [[User:Edokter]] {{talk}} 19:30, 10 April 2016 (UTC)

I just checked on Chrome 49 (Windows 7) and the the lorem ipsum test in {{intmath/testcases#Text style inline formulae}} has no overlap and no line spacing disturbance. The only case of overlap I see is when the {{math}} template is not used for the Maxwell's equations in the No {{math}} section. When using the {{math}} template, the issue does not appear. I know that there are lots of other platforms... Now, I'm at a loss on how I could try to improve the HTML+CSS math typesetting, since CSS fine-tuning is not an option... — Tentacles^{Talk or ✉ mailto:Tentacles} 23:44, 10 April 2016 (UTC)

∫ doesn't render in the same font and vertical alignment as the other integral symbols

∫ doesn't render in the same font as the other integral symbols, although on (Mathematical Operators – Unicode), they all render in the same really nice font. Furthermore, the font in which ∫ renders doesn't have the same vertical alignment as the font in which other integral symbols render.

Integral symbols shown in HTML+CSS (font-size: 2em) using the {{math}} template

∫	∬	∭	∮	∲	∳	∯	∰
int	iint	iiint	oint	varointclockwise	ointctrclockwise	oiint	oiiint

NB:

• Applying font-style: italic; or font-style: oblique; to the int integral symbol (which currently renders in a different font, which also have a higher vertical alignment) has no effect in Firefox (it remains upright), while it italicizes all the other integral symbols. E.g.

  <span style="font-style: normal;">∫ ∬ ∭ ∮ ∲ ∳ ∯ ∰</span> yields ∫ ∬ ∭ ∮ ∲ ∳ ∯ ∰;

  <span style="font-style: italic;">∫ ∬ ∭ ∮ ∲ ∳ ∯ ∰</span> yields ∫ ∬ ∭ ∮ ∲ ∳ ∯ ∰;

  <span style="font-style: oblique;">∫ ∬ ∭ ∮ ∲ ∳ ∯ ∰</span> yields ∫ ∬ ∭ ∮ ∲ ∳ ∯ ∰.

— Tentacles^{✉ mailto:Tentacles} 22:48, 13 March 2016 (UTC)

The integral symbols used are highly dependent on the fonts installed on your computer. Since int is quite common, but the others aren't, they may differ in rendering. Not much we can do about it, as forcing a specific font (or CSS metrics) may cause failure on other systems. -- [[User:Edokter]] {{talk}} 10:10, 14 March 2016 (UTC)

In IE, except for int, all the integrals seem to render in the beautiful font 'Lucida Sans Unicode', but in Firefox we get this ugly font (it is passable for text style, but would be really ugly in display style)! In which [ugly] font do the integral symbols, other than int, render? Also, in which font does int render? Finally, which font can we assume to be installed on the typical user's computer? — Tentacles^{✉ mailto:Tentacles} 18:01, 21 March 2016 (UTC)

You can't asume any font being installed, especially when it comes to unicode. Modern browsers like Firefox, but also Windows 7 and beyond, decide by themselves which font to use when a glyph is not part of the default font. Forcing a font may negate that functionality and actually break the display of non-common characters. That is the reason why the {{unicode}} template has been disabled recently. -- [[User:Edokter]] {{talk}} 18:39, 21 March 2016 (UTC)

Template_talk:Intmath/doc or Template_talk:Intmath?

I wonder whether or not I did the right thing: I created this page (Template_talk:Intmath/doc) but I wonder whether I should have created Template_talk:Intmath instead. What is the rule/convention? Should we move this page to Template_talk:Intmath or is it OK as it is? — Tentacles^{✉ mailto:Tentacles} 16:41, 21 March 2016 (UTC)

Yes its more standard to have it as Template_talk:Intmath. I've now moved the page there with a redirect so people should be able to find the discussion. --Salix alba (talk): 17:17, 21 March 2016 (UTC)
