3 X 1 Grid

Here's the code for a 3 X 1 grid usable on an HTML Content tab compatible with iOS and Android

You will find 3 dots underneath the icons these need to remain in the layout to allow the fixed position to work, you can change the colour on the dots to be the same as the background colour by using the text editor in the content tab
