“ For example, many e-readers can handle only a very tiny subset of CSS. You should not use CSS for any content that must be shown even if the reader doesn't support any CSS. For example, using CSS counters to number lists or :after selectors to add dots after list numbers will result in the wrong thing being shown to users without CSS. As a rough guide, if it can't be copy-and-pasted, users will not see it when CSS is not available. ”

“ You may sometimes also need to override the styling for some templates (some newer templates are explicitly designed to be styled from Page styles) , in which case you'll find the right classes with a .wst- prefix on that template's documentation page.
NB! If a template does not document overridable classes then it is not safe to style it, even if you notice a class it uses. Internal classes in templates can change at any time and it is in general not possible to detect and update any outside uses of that class. ”

“ The heading for the page number column is a bit off, and the chapter title "Annotated Analysis" is way off. The reason is that these two cells deviate from the others in the table: we've coded both of them to span both columns so they are getting styled as both the ":first-child" and the ":last-child". So because these two cells are different we need to add separate style rules for them. ”

“ Per-work CSS is more suitable for applying work-specific styling to generic classes. You can still target the output of templates with work-specific CSS (the template in question should set a class to allow this) .
The following are some templates set classes that can be usefully targeted with CSS (others can be found in Category:Templates applying classes for page styles) :
{{pseudoheading}}: The overall heading element has .wst-heading (search for .wst-heading in CSS files) . Derived templates apply other classes. {{rule}} The

element has class .wst-rule . ”

“ Therefore the selector used has to be more specific in order to override the general styles, in this case by specifying the element type (td) in addition to the class name.
With that in place the final rendering will be:
Other tables No left or right outer border A common style for tables is with thin borders around all cells, including the outer edges of the whole table, except for the left and right outer edges. ”
