Always use mono-space font for Chrome input fields
nb: this answer is now redundant as Chrome has removed support for user style sheets. I'd suggest dear reader to refer to the other answer, although I haven't tested it myself.
You could add a rule along the lines of
textarea { font-family: monospace !important; }
to your user stylesheet.
I found this post explaining where to find that file on common operating systems:
For Chrome, you need to find the Custom.css file. On Windows Vista/7/2008, it is located at the following (replace with, ahem, your user id):
C:\Users\<your-userid>\AppData\Local\Google\Chrome\User Data\Default\User StyleSheets\
[Presumably on Windows XP it will be under C:\Documents and Settings\ in a similar location.]
For Mac OS X, it is at:
~/Library/Application Support/Google/Chrome/Default/User StyleSheets/
On Ubuntu Linux it is found here:
~/.config/google-chrome/Default/User StyleSheets
You can use the Stylish add-on (for Firefox or Chrome), which enables you to specify custom CSS stylesheets for any website.
To make all pages use monospace fonts:
- Install Stylish
- Click the Stylish icon
- Click “Create New Style”
- Paste the code
textarea { font-family: monospace !important; }
- At the bottom of the screen, set to which URLs it should apply
- Click “Save” on the left
If you want a global style that applies to all websites, you should include the code
/* i really want this to be global */
in your stylesheet, per the Stylish help.
