Spacing[επεξεργασία]

Note that TeX handles most spacing automatically, but you may sometimes want manual control.

Feature Syntax How it looks rendered
double quad space a \qquad b <math>a \qquad b</math>
quad space a \quad b <math>a \quad b</math>
text space a\ b <math>a\ b</math>
text space without PNG conversion a \mbox{ } b <math>a \mbox{ } b</math>
large space a\;b <math>a\;b</math>
medium space a\>b [not supported]
small space a\,b <math>a\,b</math>
no space ab <math>ab\,</math>
small negative space a\!b <math>a\!b</math>

Align with normal text flow[επεξεργασία]

Due to the default css

img.tex { vertical-align: middle; }

an inline expression like <math>\int_{-N}^{N} e^x\, dx = 2 \sinh N</math> should look good.

If you need to align it otherwise, use <font style="vertical-align:-100%;"><math>...</math></font> and play with the vertical-align argument until you get it right; however, how it looks may depend on the browser and the browser settings.

Also note that if you rely on this workaround, if/when the rendering on the server gets fixed in future releases, as a result of this extra manual offset your formulae will suddenly be aligned incorrectly. So use it sparingly, if at all.

Forced PNG rendering[επεξεργασία]

To force the formula to render as PNG, add \, (small space) at the end of the formula (where it is not rendered). This will force PNG if the user is in "HTML if simple" mode, but not for "HTML if possible" mode (math rendering settings in preferences).

You can also use \,\! (small space and negative space, which cancel out) anywhere inside the math tags. This does force PNG even in "HTML if possible" mode, unlike \,.

This could be useful to keep the rendering of formulae in a proof consistent, for example, or to fix formulae that render incorrectly in HTML (at one time, a^{2+2} rendered with an extra underscore), or to demonstrate how something is rendered when it would normally show up as HTML (as in the examples above).

For instance:

Syntax How it looks rendered
a^{c+2} <math>a^{c+2}</math>
a^{c+2} \, <math>a^{c+2} \,</math>
a^{\,\!c+2} <math>a^{\,\!c+2}</math>
a^{b^{c+2}} <math>a^{b^{c+2}}</math> (WRONG with option "HTML if possible or else PNG"!)
a^{b^{c+2}} \, <math>a^{b^{c+2}} \,</math> (WRONG with option "HTML if possible or else PNG"!)
a^{b^{c+2}}\approx 5 <math>a^{b^{c+2}}\approx 5</math> (due to "<math>\approx</math>" correctly displayed, no code "\,\!" needed)
a^{b^{\,\!c+2}} <math>a^{b^{\,\!c+2}}</math>
\int_{-N}^{N} e^x\, dx <math>\int_{-N}^{N} e^x\, dx</math>


This has been tested with most of the formulae on this page, and seems to work perfectly.

You might want to include a comment in the HTML so people don't "correct" the formula by removing it:

<!-- The \,\! is to keep the formula rendered as PNG instead of HTML. Please don't remove it.-->

Color[επεξεργασία]

Equations can use color:

  • {\color{Blue}x^2}+{\color{Brown}2x}-{\color{OliveGreen}1}
    <math>{\color{Blue}x^2}+{\color{Brown}2x}-{\color{OliveGreen}1}</math>
  • x_{1,2}=\frac{-b\pm\sqrt{\color{Red}b^2-4ac}}{2a}
    <math>x_{1,2}=\frac{-b\pm\sqrt{\color{Red}b^2-4ac}}{2a}</math>

See here for all named colours supported by LaTeX.
