DETAILS

This site uses a jQuery lightbox (image gallery viewer) to display the figures
in the main content in a full screen mode and allows the user to cyle through
all the images on a page.

The lightbox used is Lightbox2 by Lokesh Dhakar, the plugin and associated
files are available at: http://lokeshdhakar.com/projects/lightbox2/.

The installed version is v2.8.2.

The jQuery plugin uses this CSS file to format the images and apply
titles, greyed out background etc.

The origninal file has been modified to adopt the fonts used in the
Practical Series website and to adapt the location of certain files to the
PS folder structure.

Further changes have been made to accomodate the column layouts of the
website.
