Tagline Twentyseventeen theme divide into two rows

First step would be to create a Child Theme: https://codex.www.ads-software.com/Child_Themes

Once I create the child theme I can inject the html and css?

Yes, but the injection will be manually through editing the code. Were you expecting something else?

As in placing it within the functions.php of the child theme correct? sorry I am not very experienced with wordpress

Something like that yes, I was just checking if you were okay with code modifications.

Is there some documentation on how I would set up once of these functions?

Does anyone know how I could alter the code or find maybe some documentation on this?

Yes, but I’m waiting for you to set up a Child Theme first. The answers on the forums are more conversational instead of something you’d see at stackoverflow.

Create a ‘header’ folder inside your Child Theme, then inside that header folder create a new file named ‘site-branding.php’.

Give your child theme ‘site-branding.php’ file all of the code from this page: https://pastebin.com/raw/aSacmiHT

The next step will be styling it.

When I do this it does not show up in the live website but I can see it when making changes to the website in the customization section of the wordpress dash board.

It was showing up last night and now it is no longer displaying, has there been an update to the theme? Even so wouldn’t the child them prevent this from affecting it?
