Note: I was trying with `<span>` tags too, but that tag is inline, so I can't
set `width` property for it.
+> In the poll plugin, I ended up using a `<hr>` for the progress-like

+> divs. Since the hr is an element they display, just setting its width can
+> make a basic progress-type display. The style then makes it display
+> better in more capable browsers.
+>
+> The other advantage to that approach is that the htmlscrubber lets
+> through the `class` and `width` fields, that are all that are needed for
+> it to work. No need to work around htmlscrubber.

Default CSS styles for the plugin can be like below:
div.progress {
Any comments? --[[Paweł|ptecza]]

+>> Below is the CSS I've been using -- [[Will]]
+
+ div.progress {
+ margin-top: 1ex;
+ margin-bottom: 1ex;
+ border: 1px solid #888;
+ width: 400px;
+ background: #eee;

+ div.progress-done {

-Here is a potential documentation page:
-
------
-
-[[!template id=plugin name=progress author="[[Will]]"]]
-[[!tag type/meta]]
-
-Provides a \\[[!progress ]] [[ikiwiki/PreProcessorDirective]] that is
-replaced with a progress bar.
-
-There are two possible parameter sets. The first is a single parameter
-`percent` which holds a percentage figure for how complete the progress bar is.
-
-The second possible set of parameters is a pair of [[ikiwiki/PageSpec]]s,
-`totalpages` and `donepages`. The progress plugin counts the number of
-pages in each pagespec and shows the percentage of the total pages that are
-done.
-
-This plugin is included in ikiwiki, but is not enabled by default.

-If it is turned on it can show what percentage of pages have discussion pages:
