This doesn't set the right CSS if I change page from article to page... Thanks

Unless you have a ton of CSS you should add the CSS for all the nodes and use the node type class on the wrapper div of the node.

I can't remember the exact classes you can view them in the source. You could do something like this

.node {}
.node-page {}
.node-blog {}

Where the first class is on all nodes and the latter is dynamic for the node.

  • This is a way but i want to add css conditionally on a page based on a node type.. problably i dont understand what you tell me....sorry for english.. Jul 13, 2011 at 15:29
  • It's simple: do not use conditional css files (unless they are very, very large). Use the css selectors like div.node-blog instead to target specific content types. Jul 13, 2011 at 15:39
  • I dont understand how to use the selector to modify all the style of a page and not one single css property.. Jul 13, 2011 at 15:48
  • Also, if you're using a sub-theme such as Zen, it gives you handy classes in the body tag with details of the content type.

  • Body classes are not limited to the Zen theme. Both D6 and D7 generate a number of body classes, regardless of the theme (but it's up to the theme to print them). This means that you can target every element in your page with a selector based on the body class. For instance: body.node-type-blog a { color: #C00 } would color all links red when viewing a blog node. Jul 13, 2011 at 21:19
