Hi there,
thats something you probably want to ask Elementor, as they may have some controls for the icon box that stop the text-align center from affecting the list.
But if they can’t help, try adding this CSS:
.elementor-widget-icon-box .elementor-icon-box-wrapper ul {
text-align: left;
}
Or this if you want to kept the list centered with the bullet aside of it:
.elementor-widget-icon-box .elementor-icon-box-wrapper ul {
text-align: left;
display: inline-block;
margin-left: auto;
}
