Huddle landing page with curved sections using HTMl and CSS

Hi, your UI is looking perfectly fine.

However,I have noticed that your styles are breaking for screen size < 375px, due to the your community-container and flowing-conversation-container, use flex-direction:column for these two containers.

And, most of the mobile screens are above 360px so try to use media queries which can includes all the mobile screens, i.e.

@media only screen and (max-width: 767px) {
/* Styles for mobile devices and tablets go here */
}
