I'm trying to write some code to cause a transition on load, so I basically have some jquery adding a class, transition-left to a div and some css that says to move left if it has the class transition-left. However, even though the class is being added, the transition isn't happening. I just don't know why that is the case. Here is my code.
$(document).ready(function () {
$("#curtain-left").addClass("transition-left");
});
$(document).ready(function () {
$("#curtain-right").addClass("transition-right");
});.curtain {
width: 100vw;
height: 100vh;
overflow: hidden;
z-index: 0;
/* CSS variables to prevent duplication below */
--piece-width: 100px;
}
.curtain .content {
/* I used flex since I'm more comfortable with that, but you can use floats if you prefer. */
display: flex;
align-items: center;
justify-content: center;
width: 100%;
height: 100%;
z-index: 0;
}
.curtain-panel {
display: flex;
align-items: center;
position: absolute;
width: 50%;
height: 100%;
transition: left, right;
transition-duration: 3s;
}
.curtain-panel.left {
left: 0;
justify-content: end;
}
.curtain-panel.right {
right: 0;
}
.curtain-panel::before {
content: "";
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
z-index: 1;
background-color: #333;
}
.curtain-piece-left {
width: var(--piece-width);
height: auto;
z-index: 2;
margin: calc(100% - var(--piece-width) / 2);
}
.curtain-piece-right {
width: var(--piece-width);
height: auto;
z-index: 2;
margin: calc(var(--piece-width) / -2);
}
.transition-left{
left: -100%;
}
.transition-right{
right: -100%;
