Huddle landing page curves HTML, CSS, Vanilla JavaScript

• Absolute/relative positioning is just for css. It may be helpful with your section/curve border positioning. Take a look at this article

For the JavaScript email input box

• I would add a placeholder to the input, [email protected]
• onClick or onSubmit of the Subscribe button, capture the user input and run a function to validate the email input. I would probably use some kind of regex for this. Research "JavaScript email validation regex"
• if the validation function returns true display some kind of confirmation to the user that their email was captured. This can be an alert or maybe a div underneath the input box. If the validation function returns false, ask the user to input a valid email

• Try adding more top margin/padding to the footer and the sections you can do this in your media queries.

• You can also try placing the border images outside of the section with a top and bottom margin of 0 and updating the sections' background-color.

• Maybe look into absolute and relative css positioning.

Hope that helps!
