Hiding long blurbs

[nou]

Update to the below, 20 July 2020: You can now use the new(ish) <details> element for hiding long blurbs instead of our custom <div class="blurb"> thing; see e.g. the Crystal Palace locale page.

To make this work, enclose your blurb like so:

<details>
<summary name="Crystal Palace"></summary>
Several paragraphs about Crystal Palace.
</details>

Original post from July 2017: I've added a thing to let us hide long blurbs on locale/category pages, since although it's good to have this info, it can end up pushing the lists of actual things in the locale quite a long way down the page.

To make this work, enclose your blurb like so:

<div class="blurb">
My very wordy essay on the history of Harefield.
</div>

You can see this in action on the Ickenham locale page, which has a great but long blurb written by katstevens.

Comments welcome!
