Is my modal not showing because of z-index? - css

Question

I'm creating an app-look-a-like mobile version of my site. In the bottom, there is a menu icon that should trigger a modal when clicked, however this is not happening, the modal is not showing. I'm not sure if this is happening because of the z-index. If so, is there a way I can solve this using only CSS? I'm using Bootstrap 4.
Here's my codepen
.footer-container-mobile {
position: fixed;
bottom: 0;
left: 0;
right: 0;
z-index: 10;
height: 54px;
background-color: #8ABE57;
width: 100%;
margin: 0 auto;
padding: 10px 40px;
box-shadow: 0px -4px 8px rgba(0, 0, 0, 0.1);
}
.footer-container-mobile i {
color: white;
font-size: 1.3em;
margin-top: 5px;
}
.circle-btn-mobile {
width: 70px;
height: 70px;
border-radius: 50%;
background-color: #31353C;
color: white;
text-align: center;
align-items: center;
font-size: 2em;
filter: drop-shadow(0px 0px 4px rgba(0, 0, 0, 0.30));
display: flex;
flex-direction: row;
}
.circle-btn-mobile-container {
width: fit-content;
margin: 0 auto !important;
z-index: 50;
position: fixed;
bottom: 12px;
left: 0;
right: 0;
}

Answer 1

You can't handle click event using CSS/HTML. Alternatively, you may use :hover, :focus, :active pseudo-classes using CSS. You may find more pseudo-classes here. I highly recommend to use JS in your situation in order to have better control on HTML elements. You may check the JS click event example here.

Answer 2

I made a rookie mistake.
I forgot to add the data-target="#idHere" to my <a href="#">
By adding this, I solved my issue. Thanks for the help anyways, made me realize my mistake.

Answer 3

First off, you have 2 elements that have the same ID, which is a problem:
<i class="far fa-bars">Menu icon</i>
<div class="modal fade" id="modalServiceMenuMobile" tabindex="-1" role="dialog" aria-labelledby="modalServiceMenuMobile" aria-hidden="true">
What you need to do is:
Give the div that's gonna be your modal a unique ID different from the link that's trying to open it.
Give the a element calling the modal the data attribute data-target="#[name_of_modal_id]". It's important that you have the # symbol before the modal ID you're trying to reference. Example: data-target="#modalDiv".
