Here are two screenshots of how it looks on my device:

This does work for me. Is your css file called "screen.css" and in the same directory as the html file? File names are case sensitive in iOS, so something like "Screen.css" won't work!

What does your html file look like?

You can add custom syntax definitions to Textastic by using TextMate bundles. See

Please try to enable the "Debug Log" setting in the connection's settings screen. Tap on the (i) button on the right side of a connection to change its settings. This creates a log file when you try to connect to the server which might help you find out what's wrong.

Hello,

1.) yes, you can just create a new file with a .css file extension
2.) you can add a link to your CSS file like this:

<link rel="stylesheet" href="example.css" type="text/css" />

Textastic is not scriptable at the moment.

But, if you add the AppleScript Editor to System Preferences -> Security & Privacy -> Privacy -> Accessibility, you can use the following commands:

get:

tell application "System Events" to tell application process "Textastic"
get size of window 1
end tell

set:

tell application "System Events" to tell application process "Textastic"
tell window 1
set {size, position} to {{1280, 800}, {50, 50}}
end tell
end tell

Unfortunately I can't reproduce this issue on my iPad.

Can you maybe send me a screenshot or small video demonstrating the issue?

For the moment, you can add this syntax definition yourself.

This is explained in the manual: http://www.textasticapp.com/mac/manual/lessons/How...

The Arduino bundle can be found here: https://github.com/nasser/arduino.tmbundle

I will add Arduino support in the next update of the Mac version.
