Hi @yepezjuan,

Good job on your first submission! You followed the instructions to add the "github-handle" line and indent using spaces and completed the main request, just a couple of things:

1. I think you might have missed the screenshots section with the before and after pictures (if applicable). Can you update it to include pictures, or if there's no visual changes just say "No visual changes to the website" (I think it's included in the template, that's what I put for my pull request since mine didn't have any).
2. Check the appropriate checkbox under the "CodeQL Alerts" section. You can find the results of the scan further down your pull request (all checks passed for yours so you can just search "All checks have passed" to find where it is for future reference.
3. Some minor formatting issues under "What changes did you make" and "Why did you make the changes" with the empty bullet points. You can just remove those if there's nothing there.

Just get those addressed and it'll be perfect! Let me know once you do so I can approve this.
