This makes it easier to keep baseline alignment between labels and their
respective inputs. Declaring `margin-left: 51%;` for the post-input notes
is not exactly what we want, but it's much closer and less troublesome than
dealing with the vertical alignment of labels otherwise.
* Separate out amount-parsing and reacting into separate events. This sets
the stage for other elements to react to the custom
'conservancy:newamount' event.
* Set up events in the context of each supporter form, with closures. This
lets us avoid weird CSS selector gymnastics in the event, and instead
drill down from the form to find the elements we need.
There are no functional changes in this code, barring bugs.
* Add an animation for state changes.
* Set the start state by triggering the event on the selection at page load.
Firefox at least remembers the selected button on page load. This avoids
a situation where the user says they want a shirt, reload, and now the
size selection is invisible because we used to hide that unconditionally.
This commit keeps the presentation basically the same, it just moves
presentation rules out of HTML and into CSS. It's not pixel-perfect but
pretty close.
The rationale given in the comments for these rules no longer applies: there
are no divs with class column or conservancy-blog on any pages. Meanwhile,
they're causing unwanted styling: we started using the column class on the
front page for two-column layout, and the videos are appearing smaller than
desired there. Just remove these.
This avoids a situation where multiple summaries have floats that stack on
top of each other vertically, which end up getting far away from the actual
text.
In order to make this work, we had to change the styling of #mainContent on
blog pages (and others with a sidebar). Otherwise, headlines with
class="clear" would clear the sidebar as well.
With a valid URL, a past donor can upgrade to a supporter by donating
the rest of the amount. Django validates the data and, if it passes,
puts it in the form. The JavaScript does most of the work from there.
