RE: Sunny's "Mobile first using pure HTML and CSS" solution0You've done a really good job on this challenge, Sunny! Both your HTML and CSS look good. The only small thing I'd recommend would be to remove the br tag from the h1. Instead, I'd just let the width of the element dictate how the text flows. Forcing a break in text can cause issues, especially with responsiveness. Although your heading looks fine on all screen sizes, I'd recommend avoiding it in the future.Keep up the great work!
