# Project 29

[Our migration guide](/migration-guides/widget-migration/guide)

## What made you smile?

- Much easier than last week's project
- Focus


## What did you find confusing?

- Wide code sample with diff? Scroll right highlighting is gone

- Webview updates slowly for Shiki code sample changes (while regular Markdown pages are quick) -- this is probably due to what seems like a page refresh.
- `{% highlight` is used with both regex to highlight a word (which uses the code `word` in the comment syntax) and line numbers to highlight lines (which does use the `highlight` word in comment syntax). Should it be `word-highlight`?
- There are some color contrast issues in dark mode for certain code highlights such as diff and warning.

- We couldn't get highlight to work with any non-exact match regex, for example: `highlight="/id=\".*\"/gm"`. If it actually doesn't support regex, we shouldn't say that it does in our docs. The [Shiki transformer website](https://shiki.style/packages/transformers#transformermetawordhighlight) doesn't use the word regex.
- `highlight={}` crashes the webview (without quotes)
