PR Description

This PR combines Steps 21 and 22 of the Responsive Web Design project to build a cat painting into a single step. The updated step now instructs learners to create two div elements, one inside the .cat-left-ear element with the class cat-left-inner-ear and another inside the .cat-right-ear element with the class cat-right-inner-ear.

Then using the doc guide at: https://contribute.freecodecamp.org/how-to-work-on-practice-projects/#how-to-work-on-practice-projects

I have delete step 22.

Moving on, I have combined Steps 41 and 42 of the Responsive Web Design project as well in this PR according to the comments mentioned in the original thread.

Note: The updated steps were 40 and 41 when changes were made to them (due to deletion of step 22).

Following on, I deleted the updated step 41 to ensure that duplication is removed from the codebase.

All tests were also updated for the combined steps.

All changes have been tested locally to ensure the instructions work as expected and do not disrupt the learning flow.
