1. add new page "login"
2. add new page "success"
3. creating form with validation
4. add to the form checkbox and button
5. success message with animation

❗️ I’m not sure what I did, but my changes to the repository with task #3 were somehow uploaded to the Main branch without approval and merge from the mentor, so I’m making a pull request again so that the mentor can check it.
