Chameleon is a Moodle theme with an option to interactively change your theme within your browser page. You click on an element to change it's style. Please read the Chameleon Moodle Docs explanation for more information about Chameleon's interactive theme work.
To enable editing you change "$THEME->chameleonenabled = false;" in the config.php file in your Chameleon theme folder to true. It is recommended to change "$THEME->chameleonenabled = true;" back to false again once you're satisfied with your theme because the editing engine loads several extra files into the browser. Therefore the page loading speed is reduced.
If you want to hand code styles you must not write hooks as comma separated lists of elements like
td#middle-column div.bt,
div#middle-column div.bt {
...
}
in Chameleon themes because the Chameleon engine can't handle these comma lists.
Please write two separate statements instead.
td#middle-column div.bt {
...
}
div#middle-column div.bt {
...
}
