IE doesn't load more than 30 stylesheets (drupal)?

I have a page that calls about 32 stylesheets. On another page, it calls < 30. In every other browser both pages look fine, but on the first page in IE (8, 7), the 开发者_运维知识库last 2 stylesheets aren't being called and it totally messes up the layout. I'm not really sure how to get around this in drupal.

EDIT: Also, I understand that having more than 30 is not that great, but that is how our site was developed originally. We have a bunch of themes and modules that add syleshets using "drupal_add_css".

I tried compressing the css by going to admin/settings/performance but the stylesheet link doesn't work because we are using a port number for our test site (http://mysite:123) and the link generated is http://mysite/public/css/random_string.css

You can use admin/settings/performance and set Optimize CSS to true. This will put out 1 css instead of 32+. If you are developing and want this on to work in IE, you need to clear the cache after changing your css. We tend to leave this off in development & only turn it on to test in IE or for production.

All best, ember

Hi AlisonC,

I've never tried using a port for a site with Drupal. I'd suggest making sure your settings.php for your site are setup correctly. There may need to be a special name for your folder (see the instructions at the top of settings.php) or you may need to check the $base_url and make sure it has the port.

If that doesn't work, there's a module for caching css while developing (http://drupal.org/project/ie_css_optimizer). I haven't used it, but it may work a little differently at least for your situation. (After typing this I noticed another user also recommended it).

I've been assuming you're still developing, and I would remove the ie css optimizer module (or at least turn it off) before going live, since it's primarily a developer helper. I think this is the limit of my knowledge. Good luck!

This is a known limitation with IE - you cannot have more than 31 stylesheets on any given page.

The only real solution you have is to combine your stylesheets so you have fewer individual CSS files (use Drupal's "Optimize CSS" option). But I acknowledge this may be a pain if you're trying to debug your code, etc.

In fact, it is possible to load a lot more than 31 stylesheets into IE, but for any more than 31, you need to do it via an @import line inside another CSS file. This isn't really possible in the context of a Drupal site, where each stylesheet is added by a module, and you don't really have control of how Drupal adds them to the page.

How are they being loaded? 30 individual <link href="blahblah.css"> calls? Or from other stylesheets with @import directives? Remember that if there's a syntax error, further processing of a stylesheet will fail.

http://drupal.org/project/ie_css_optimizer ...is what we use. Theme debugging is a pain with CSS optimization turned on. D7 uses the @import method this module implements to get around the issue.

There is actually a module to deal with this. I haven't used it personally but it does have 5K+ users (Drupal 6).
