A Mortgage calculator using HTML, CSS and JavaScript

What are you most proud of, and what would you do differently next time?

I added a screenshot as an image to the content for the project to look more close with the design. The image colour was different from the background colour I earlier applied to the parent element. I was able to mix the colour with rgb() to eliminate the obvious difference and I got the desired colour. This makes me proud

What challenges did you encounter, and how did you overcome them?

I couldn't style with CSS when it is checked. I had to leave it like that

What specific areas of your project would you like help with?

I am a novice in JavaScript. I would like my code to be reviewed more in this area

Another thing is inability to style with CSS when it is checked
