My process

Built with

  • Plain JavaScript
  • Tailwind CSS
  • Flexbox

What I learned

  • Set up project with parcel and tailwind source
  • Don't override the font size, this leads to a lot of custom classes in tailwind like mb-[2.6rem] 
    html {
    font-size: 62.5%; /* 10px */
}
  • Make a border with color gradient 
    .form-input:active,
.form-input:focus,
.form-input:hover,
.form-input:not(:placeholder-shown) {
    background:
            linear-gradient(white, white) padding-box,
            linear-gradient(to bottom, #6348FE, #610595) border-box;
    opacity: 1;
    border: 1px solid transparent;
}

Continued development

  • Tailwind CSS
  • Develop mobile first, since Tailwind's approach is more mobile first
