Chrome not being pixel perfect when a is display: block

As you can see in [this][1] fiddle, on hover the hover-state of a always is one pixel higher than the ul. (You can see this in the fiddle: it even gets over the border of ul) This only happens in Chrome (also tested in FF en IE10, but they don't have that problem). Any solution to that?

Note: overflow: hidden is not a solution, because I want overflow to be visible for other stuff (sub-menus among others). 

ul {
  list-style: none;
  text-align: center;
  background: whiteSmoke;
  border: 1px solid red;
}
li {
  display: inline-block;
  font-size: 150%;
  position: relative;
  margin: 0;
}
li a {
  color: #555;
  text-decoration: none;
  text-shadow: 0 2px 0 white;
  display: block;
  padding: 0.2em 0.5em 0.3em;
}
li a:hover {
  color: black;
  background: whiteSmoke;
  box-shadow: inset 0 2px 5px rgba(0, 0, 0, 0.125);
}
<nav>
  <ul>
    <li><a href="#">Home</a></li>
    <li><a href="#">Forum</a></li>
    <li><a href="#">About</a></li>
    <li class="has-sub-menu"><a href="#">Contact</a></li>
  </ul>
</nav>

Solution

  • If your menu is one pixel low in Chrome; there are two browser-specifc approaches that could apply correctional styling only in Chrome. See Similar Post Answered

    CSS

    @media screen and (-webkit-min-device-pixel-ratio:0) { 
  position:relative;top:-1px;
}

    JS

    if (navigator.appVersion.indexOf("Chrome/") != -1) {
  // modify menu styling 
}
