I’ve added some custom CSS and HTML. Checked the preview, and everything looks great.
Now I want to commit these changes, but how? I don’t see any commands for this, and I tried rebuilding the discourse app, but nothing happens.
My searches come up empty. This is probably so easy, nobody ever asked how to do it, but this noob could use a hint…

Seems irrelevant but I don’t really understand.

Where? Custom Theme, default theme?
Common css / desktop css / mobile css?
More details on what you have done will be helpful.
Usually you just select a theme `/admin/customize/themes` and do this:
Once you hit that save button, changes show up pretty much instantly as long as the theme you have edited is active.

What you did. In the video. Except I can only see the changes when I hit the Preview button.

Have you got the theme selected as the active default theme? See the green tick?

Yes. I’ve edited the standard light theme, and it’s active and default.

I’ll post the content of the Header in a bit. The forum keeps rendering the html when I paste it…

This is wrong, it should be
```
nav#bar #logo {
display: flex;
justify-content: center;
flex-basis: 100%;
}
```

That’s it! Well spotted, you’ve got a keen eye!
Funny that the preview didn’t mind that syntax error.

Glad you got it working 😄
- Any errors in your CSS will render that CSS void.
- I’ve never used preview before so I can’t comment on that.
- I’m sure there used to be an error notification on the page 🤔
Oh and Happy Birthday @tshenry 🎉 Have a good one
