If the site doesn't build locally, that's my problem here. I'll get it sorted tonight.

Done. I still have to fix some stuff with toh-6, but now the site should compile without problems.

Nice work so far! One thing though: do not modify anything in <?code-excerpt> directly. This part is automatically updated/generated by our code excerpt generation tool. If you need to change the files, change their relevant example Dart project located in examples/ng/doc/<project-name>. For example, if you're working on lifecycle hooks, update the code inside examples/ng/doc/lifecycle-hooks. The corresponding source file name is included in the <?code-excerpt> block. After that, run grind create-code-excerpts and grind update-code-excerpts.

Also, the code in lifecycle-hooks is very out-to-date. If you're having trouble running and building that project, I'll take care of that tomorrow.

I am getting errors due to missing toh-6 directory.

I am going to update whole lifecycle article. But for now, deprecation of OnChanges is the first step.

Refetch the Git submodules: git submodule update --init --remote --recursive.

You can also enable CI in your fork if it's costly to build the site locally.

Looks good to me so far. I can help generate the GIFs this weekend if I can fix my PC before that.

Do you have a 2.12 SDK to check whether Angular 7 can actually run for Dart versions below 2.14? I think theoretically Angular 7 is only for 2.14+ (see here), but I never verified it by myself.
