Quick Tip - Make Apache's Directory Indexes Look Nicer on Mobile
If you use Apache, then you most likely have DirectoryIndex enabled on your development server. This is the feature that lets you request a directory without a home document and see a list of folders and files. This is notnormally enabled in production, but in certain circumstances it may be. (For a file download directory perhaps.) If you do any testing with mobile devices though you will probably find this index to a be a bit hard to read. Here's an example.
You can pinch and zoom to make that a bit easier to read, but it's a pain in the rear. Turns out Apache has a few options that allow you to customize how this index file is created. One of them, IndexHeaderInsert, allows you to add HTML to the head section of the document. I added the following to my Apache httpd.conf file:
IndexHeadInsert "<meta name=\"viewport\" content=\"width=device-width, initial-scale=1\">"
