I wrote a while ago about how much I like Mailplane for handling Gmail on my Mac: Mailplane makes Gmail so much smoother.
Mailplane has a nifty slider in the Preferences for making fonts bigger (or smaller) and I’d cranked thing up a bit to make it easier to read.
A message with close together lines.
But something still niggled: when I opened an email message the lines of text were too close together. I needed a way to increase the line-height.
Mailplane accepts CSS files
In Mailplane’s prefs there is a place to choose your own stylesheet. That seemed the obvious way to go with my line-height problem.
I struck an immediate huge glitch though: when I viewed the source of an email message (using another browser) I just couldn’t figure out what selectors to use. All I seemed to be able to do was to make everything in Gmail huge.
A question on the Mailplane mailing list led me to a forum post that led me to a solution.
My Mailplane stylesheet
Larger font and more line-height.
Here’s my new stylesheet, with a better and larger font and more line-height. I hope it’s helpful for other Mailplane users:
textarea.Ak, div.ii.gt {
font-family: Georgia !important;
color:black !important;
font-size: 1em !important;
line-height: 1.5 !important;
}
How to use the code
- Copy the above code and paste it into a text document.
- Save the file as
mailplane.css. Any filename is fine, so long as it ends in.css. - Go to Mailplane Preferences — Tweak UI and check the box beside Custom Stylesheet.
- Click the Choose button beside the Custom Stylesheet checkbox, locate and Open your stylesheet.
You may need to Quit and restart Mailplane for the changes to take effect.
Now open a plain text message you have received and you should see a difference.
If you receive styled messages their styles may override what you’ve set here.
