few styles in styles.php a bit too generic

[danmarsden]

standard template text response follows... :-)

in your styles.css you define a number of generic styles that could clash with core moodle code or other locations where simliar names are used.

Moodle helpfully adds a number of classes to the body tag based on the path that you can use such as:
eg if you are have a file in mod/assign you would see the following class added to the body tag
path-mod-assign
so if you have an item with the class "filething" on the page you would target it like:

.path-mod-assign .filething {
   color: red;
}

Please make sure your css classes in styles.css are specific enough so they cannot clash with other core code.
