How to code HTML

So, hello there. This is a test HTML site for me, AceMaestro, to learn about HTML.

So there's this picture of a dog

and I think its kinda cool.

Besides all that testing, I think that you should go scroll down for a funny picture.

My mum (82F) told me (12M) to do the dishes (16) but I (12M) was too busy playing Fortnite (3 kills) so I (12M) grabbed my controller (DualShock 4) and threw it at her (138kph). She died, and I (12M) went to prison (18 years). While in prison I (12M) incited several riots (3) and assumed leadership of a gang responsible for smuggling drugs (cocaine) into the country. I (12M) also ordered the assassination of several celebrities (Michael Jackson, Elvis Presley and Jeffrey Epstein) and planned a terrorist attack (9/11). Reddit, AITA?
