I am attempting to add animation to a modal using a transition effect. My goal is to open it slowly, either from the center of the screen or from the bottom. However, I am struggling to understand how this can be achieved...
While searching on Google, I came across this code snippet:
https://codepen.io/designcouch/pen/obvKxmUnfortunately, I find the code too complex and have difficulties in adapting it to my own code...
/*Open stress popup */
// Get the modal
var hydricstressmodal = document.getElementById('hydricstressmodal');
// Get the button that opens the modal
var stress = document.getElementById("stress");
// Get the <span> element that closes the modal
var hydricstressspan = document.getElementsByClassName("stressclose")[0];
// When the user clicks the button, open the modal
stress.onclick = function() {
hydricstressmodal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
hydricstressspan.onclick = function() {
hydricstressmodal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == hydricstressmodal) {
hydricstressmodal.style.display = "none";
}
}
/*Open vegetal popup */
// Get the modal
var vegetalmodal = document.getElementById('vegetalmodal');
// Get the button that opens the modal
var vegetal = document.getElementById("vegetal");
// Get the <span> element that closes the modal
var vegetalspan = document.getElementsByClassName("vegetalclose")[0];
// when clicked, open the modal
vegetal.onclick = function() {
vegetalmodal.style.display = "block";
}
// when clicked on <span>, close the modal
vegetalspan.onclick = function() {
vegetalmodal.style.display = "none";
}
// When click anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == vegetalmodal) {
vegetalmodal.style.display = "none";
}
