Navbar Items get bigger on hover? - html

Question

I've made some changes to some buttons and now my navbar items get bigger on hover, which is a behaviour not desired.
This behaviour is more noticable when hovering on the logo in the navbar.
Codepen:

<nav class="navbar navbar-expand-md navbar-dark fixed-top navbar-bg">
<a class="navbar-brand" href="/">  <img src="https://stickers-gallito-uploaded-files.s3.amazonaws.com/static/img/stickers_gallito_logo.png" width="20px" height="30px"></a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarCollapse"
aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarCollapse">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="/stickers">Stickers <span class="sr-only">(current)</span></a>
</li>
</ul>
<ul class="navbar-nav ml-auto">
<li class="nav-item active">
<a class="nav-link" href="/carrito_de_compras/"><i class="fas fa-shopping-cart"
style="color:white !important;"></i> ( 3)</a>

aria-expanded="false"><i class="fas fa-user-circle"></i> ogonzales</a>
<div class="dropdown-menu dropdown-menu-right">

Answer 1

This is because of the footer.css Line #38:
li.footer_nav_links a:focus, a:hover {
font-size: 12px;
color: rgb(2, 214, 158);
text-decoration: none;
}
Get rid of the font-size: 12px there and it would be fine. Maybe, you are using a:hover in a generic way, so it affects all the <a> tags when hovered. Did you mean li.footer_nav_links a:hover?
li.footer_nav_links a:focus, li.footer_nav_links a:hover {
font-size: 12px;
color: rgb(2, 214, 158);
text-decoration: none;
}
