Measurements

All user interface dimensions are measured in em units, which is the height of one line of text in the user's browser. This is normally around 16 pixels, but can vary depending on the user's settings. For exmaple, some users may have their browser set to use larger text for accessibility reasons.

pub fn Example() {
    Transmission {
        P(fontSize=2) { "This text is twice as big as normal" }
        Button(width=25) { "I am a wide button" }
    }
}
