How to adjust animation linked to a hover event? - html

Question

I have a header composed of navigation links to other websites, some of these links are shown through drop-down menus. With the event hover I have added an animation and style to see what you are on at every moment and that, in case of a drop-down, shows you all the options. The thing is that once the dropdown has been shown I have added the same style and animation to the internal links as to the main ones, but in the case of the animation I always have the underline in the same place instead of just below each link. Thanks in advance for your time and help. I leave you a link with an example as I have it now working with the described behavior

Answer 1

Please add this to your code
.dropdown-menu-link {
padding-bottom:3px;
position:relative;
}
.dropdown-menu-item {
position:relative;
}
Change the code bottom:30%; to bottom: 0px;
.dropdown-menu-link:before {
bottom: 0px;
}

Answer 2

Add position: relative to .dropdown-menu-item and set a correct position to bottom of .dropdown-menu-item:before, let's say to 0px;
Or if you want to be relative to the link set position: relative to .dropdown-menu-link.
