When I display my app on a device, the fonts, icons and buttons are unusably small. This is especially true on a tablet.
How can I easily scale up all of of my UI components?
Make sure the following meta tag is included in your app html file:
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no">
If you still feel that the buttons and text are to small (which the should be a personal preference) you could always try changing the css. Add a new rule like this:
body {
font-size: 140% !important; //I believe 114% is default
}
Hope it helps.
