What was the outcome? I think it's a half-way decent copy - of course the original will always look significantly better. + +Don't care about reading through the tutorial? No problem!

That will come into play a bit later. For now, we want to lay the Blue Square on top of this newly creating White Square: + + + .blue-square { + background: linear-gradient(#04BDFD 0%, #0585E4 100%); + border-radius: 105px; + box-shadow: inset 0 5px 8px rgba(255,255,255,0.5), inset 0 -5px 8px rgba(0,0,0,0.32), 0 12px 10px rgba(0,0,0,0.18), 0 2px 4px rgba(0,0,0,0.15); + height: 420px; + left: 205px; + padding: 75px 0 0; + position: absolute; + top: 75px; + width: 420px; + } + + +## Targeting the Inner Rows + +So far so good. The next part *looks* like a lot, but I assure you it's fairly straightforward. We need to include each row inside the Blue Square like in the original Dribbble shot (7 total). First we start with the parent `row` styling: + + + .blue-square .row { + display: flex; + height: 20px; + justify-content: space-between; + padding: 0 55px; + position: absolute; + width: 100%; + } + + +Now we style each individual row item via the `nth-of-type` attribute: + + + .blue-square .row:nth-of-type(2) { margin-top: var(--row-distance); } + .blue-square .row:nth-of-type(2) .item:nth-of-type(odd) { + width: 85px; + } + .blue-square .row:nth-of-type(2) .item:nth-of-type(even) { + width: calc(100% - 100px); + } + .blue-square .row:nth-of-type(3) { margin-top: calc(var(--row-distance) * 2); } + .blue-square .row:nth-of-type(3) .item:nth-of-type(odd) { + width: 115px; + } + .blue-square .row:nth-of-type(3) .item:nth-of-type(even) { + width: calc(100% - 130px); + } + .blue-square .row:nth-of-type(4) { margin-top: calc(var(--row-distance) * 3); } + .blue-square .row:nth-of-type(4) .item:nth-of-type(odd) { + width: 185px; + } + .blue-square .row:nth-of-type(4) .item:nth-of-type(even) { + width: calc(100% - 200px); + } + .blue-square .row:nth-of-type(5) { margin-top: calc(var(--row-distance) * 4); width: calc(100% - 115px); } + .blue-square .row:nth-of-type(5) .item:nth-of-type(odd) { + width: 105px; + } + .blue-square .row:nth-of-type(5) .item:nth-of-type(even) { + width: calc(100% - 120px); + } + .blue-square .row:nth-of-type(6) { margin-top: calc(var(--row-distance) * 5); width: calc(100% - 140px); } + .blue-square .row:nth-of-type(6) .item:nth-of-type(odd) { + width: 65px; + } + .blue-square .row:nth-of-type(6) .item:nth-of-type(even) { + width: calc(100% - 80px); + } + .blue-square .row:nth-of-type(7) { margin-top: calc(var(--row-distance) * 6); width: calc(100% - 160px); } + .blue-square .row:nth-of-type(7) .item:nth-of-type(odd) { + width: 40px; + } + .blue-square .row:nth-of-type(7) .item:nth-of-type(even) { + width: calc(100% - 55px); + } + .blue-square .row .item { + background: white; + border-radius: 20px; + box-shadow: inset 0 -2px 4px rgba(0,0,0,0.06), inset 0 2px 4px rgba(255,255,255,0.1), 0 4px 6px rgba(0,0,0,0.05); + width: 40px; + } + .blue-square .row .item:nth-of-type(even) { + background: #3FC0F5; + width: calc(100% - 55px); + } + + +Take a few moments to read everything over - it will help you better understand what's going on. Basically, we are adding two inner elements to each row element. We calculate the `margin-top` distance by using that `--row-distance` variable I mentioned earlier. The inner elements are then styled based on their placement inside the row (`nth-of-type`). + +### The Play Button + +Now we finish things off with a much simpler element to style: + + + .play-button { + backdrop-filter: blur(6px); + border-radius: 9999px; + box-shadow: inset 0 4px 0 rgba(255,255,255,0.3), inset 0 20px 15px rgba(255,255,255,0.6), 0 8px 12px rgba(0,0,0,0.1), 0 4px 6px rgba(0,0,0,0.05); + height: 220px; + overflow: hidden; + position: absolute; + right: 140px; + top: 320px; + width: 220px; + } + .play-button::before { + background: rgba(255,255,255,0.9); + border-radius: 9999px; + content:''; + filter: blur(40px); + height: 150%; + left: -25%; + opacity: 0.8; + position: absolute; + top: -25%; + width: 150%; + } + + .triangle { + position: absolute; + left: calc(50% - 2em); + background-color: #315074; + top: calc(50% - 2.1em); + text-align: left; + } + .triangle:before, + .triangle:after { + content: ''; + position: absolute; + background-color: inherit; + } + .triangle, + .triangle:before, + .triangle:after { + width: 3.2em; + height: 3.2em; + border-top-right-radius: 30%; + } + + .triangle { + transform: rotate(-90deg) skewX(-30deg) scale(1,.866); + } + .triangle:before { + transform: rotate(-135deg) skewX(-45deg) scale(1.414,.707) translate(0,-50%); + } + .triangle:after { + transform: rotate(135deg) skewY(-45deg) scale(.707,1.414) translate(50%); + } + + +Thanks to [meduz](https://m.nintendojo.fr/@meduz/106059826445460903) for pointing out the `backdrop-filter` property. This allows for a frosted glass look on Chromium & Safari (although sadly not on Firefox). The `triangle` element could also be improved by using an embedded `SVG` but I was determined to use only CSS for this experiment :P + +That's really all there is to it!
