Fede kodeeksempler, som jeg bruger meget, men ofte glemmer
CSS: Animating display block to none and vice versa
@keyframes fadeIn {
0% {
opacity: 0;
display: none;
}
100% {
opacity: 1;
display: block;
}
}
@keyframes fadeOut {
0% {
opacity: 1;
display: block;
}
100% {
opacity: 0;
display: none;
}
}
.element {
animation: fadeIn 2s ease-in-out forwards;
}
.element-hidden {
animation: fadeOut 2s ease-in-out forwards;
}
CSS: Make child element break out of parent container
.container .innerContainer:nth-child(2) {
box-shadow: 0 0 0 100vmax #000000;
clip-path: inset(0 -100vmax);
background-color: #000000;
color: white;
}
CSS: Grid and min max width in CSS
.container {
display: grid;
grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
grid-gap: 20px;
}
CSS: Apply styles to every fourth paragraph except the last one
p:nth-of-type(4n + 1):not(:last-of-type) {
font-weight: bold;
}
CSS: Apply styles to every second to third div
.container div:nth-of-type(n + 2):nth-of-type(-1n + 3) {
background-color: red;
}
CSS: Margin block auto
.container {
display: flex;
}
.container div:nth-child(2) {
margin-block-start: auto;
}
