[doc] A matrix CSS style for matrices in docs #496
Description
I think the docs would be both easier to understand and nicer to look at by styling the matrices a bit more.
The matrices appear to be tables using the 'inline' class, this may be as simple as applying a CSS style. Below is the one I wrote for matrepr. AFAIK you just have to copy it to the CSS file in the statics directory then just select the class. This style was written for Jupyter so may or may not be a drop-in for Sphinx.
table.matreprmatrix {
border-collapse: collapse;
}
/* remove thin black line under Jupyter table headers */
table.matreprmatrix > thead {
border: 0px;
}
/* row indices */
table.matreprmatrix > tbody tr th {
font-size: smaller;
vertical-align: middle;
text-align: right;
}
/* col indices */
table.matreprmatrix > thead tr th {
font-size: smaller;
vertical-align: middle;
text-align: center;
}
/* cells */
table.matreprmatrix > tbody tr td {
vertical-align: middle;
text-align: center;
position: relative;
}
/* left border */
table.matreprmatrix > tbody tr td:first-of-type {
border-left: solid 2px;
}
/* right border */
table.matreprmatrix > tbody tr td:last-of-type {
border-right: solid 2px;
}
/* prevents empty cells from collapsing, especially empty rows */
table.matreprmatrix > tbody tr td:empty::before {
content: "\00a0\00a0\00a0";
visibility: hidden;
}
table.matreprmatrix > tbody tr td:empty::after {
content: "\00a0\00a0\00a0";
visibility: hidden;
}
/* matrix bracket ticks */
table.matreprmatrix > tbody > tr:first-child > td:first-of-type::before {
content: "";
width: 4px;
position: absolute;
top: 0;
bottom: 0;
visibility: visible;
left: 0;
right: auto;
border-top: solid 2px;
}
table.matreprmatrix > tbody > tr:last-child > td:first-of-type::before {
content: "";
