Add a signature in Gmail.
Make the signature here, then paste it into Gmail on a computer. About two minutes, and the formatting survives because you paste the rendered signature rather than the source.
In Gmail on a computer: Settings, See all settings, scroll to Signature on the General tab, Create new, paste, choose it under Signature defaults, then Save Changes at the very bottom of the page. The last step is the one most often missed.
Put your name in and the signature appears here.
Nothing is stored. No images and no web fonts unless you choose them, so it renders the same in every mail client.

04

Save Changes
Scroll to the very bottom of the page and click Save Changes. The button is a long way below the signature box, and leaving without it discards the signature.
