In the examples below, the text won't be allowed to decrease pass the
scriptminsize or your browser's minimum allowable font size -- this can be
set with, e.g, user_pref("font.minimum-size.x-western", 10). To see the
effect of the gradual decrease induced by changes in script levels more clearly,
you may have to increase your default font size in the menu:
"Edit -> Preferences -> Appearance -> Fonts".
Here is how the alphabet looks like at scriptminsize: a, b, c ... x, y, z
Here is how greek letters look like at scriptminsize: α, β, γ ...,
ψ, ω, ϑ, ϒ, ϖ
Here is how numbers look like at scriptminsize: 0, 1, 2, ..., 10, 11, 12, ...
You can use "View -> Text Zoom" in the usual way to zoom the MathML text along with the other text.
As a visual aid, the examples deliberately draw attention to
the math axis and the baseline: ----------------------- this is the math axis ..................... this is the baseline
External vertical align is center
, cols arg is "|r|c|l|", \hline's above and below.
When align="center" or align="baseline", the middle of the table
coincides with the baseline.
External vertical align is axis
, columnlines="solid", rowlines="dashed solid dashed".
By default -- when the align attribute
is not set, or when align="axis", the middle of the table
coincides with the math axis.
External vertical align is top
cols arg is"r|c:l".
External vertical align is bottom
cols arg is "r|cl". MathML doesn't specify how to only display certain sides
of the table border, as in "|rcl", but these can be obtained in Mozilla using
the 'border' property of CSS, e.g., "|rcl" can be achieved with the CSS
declaration "mtable { border-left: solid thin }".
Math axis test, using externally aligned arrays inside symmetric fences.
post text.
Now for a display
text after displayed math. Do you see which vertical alignment is
set on that table?
Example of \begin{matrix}
with 3 \hline's.
Example of \begin{smallmatrix}
obtained with scriptlevel="+1".
Example of \begin{pmatrix}
with an \hline after the first row.
Example of \begin{bmatrix}
Example of \begin{vmatrix}
Example of \begin{Vmatrix}
Example of \begin{Bmatrix}
A fenced matrix and the equivalent \begin{bmatrix}
.
A table with align="axis2" to anchor the table externally w.r.t. the axis
of the second row
, but this is subject to variances due to style changes, e.g., from the
scriptlevel.
. Anyway, this is buggy in Mozilla because what you see above is a fallback
to the rendering code used for the baseline case (see below).
A table with align="baseline-1" to anchor the table externally w.r.t. the baseline
of the last row
, neat isn't it? This would be pretty hard to obtain otherwise.
Contrast it with the following which has align="bottom"
,
and with this one which has align="center-1"
,
but note that setting the baseline relative to a particular row is meaningless
if the row doesn't have at least one cell with "rowalign=baseline"
where to anchor the baseline (in which case Mozilla will behave as if
it was align="center#rownumber").
These may sound like gimmicks until you want to get a damping effect
such as this
, or perhaps the reverse
, modulo pixel roundoff errors. Here 'a' and 'b' can be other combinations
of possibly irregular boxes.
And making floating elements do a multiplication such as the
following one which is anchored at a baseline is made simple by
using align="baseline1" on both tables
To multiply a matrix A by a vector x, each row of
the matrix has to be multiplied to the vector. So at the
i-th step, it proceeds thus:
