Question

所以我的网站有一个问题。当我尝试对这些“ikonka”div应用悬停效果时，它只是不起作用。我尝试将我的浏览器更改为Mozilla Firefox，但它很有效，但不幸的是它只运行了几次。当我尝试在Google Chrome工具上手动转动悬停效果时，它可以正常工作。顺便说一下，我正在使用fontello图标。这是我的HTML：

window.onscroll = function() {
  myFunction()
};

var navbar = document.getElementById("navbar");
var sticky = navbar.offsetTop;

function myFunction() {
  if (window.pageYOffset >= sticky) {
    navbar.classList.add("sticky")
  } else {
    navbar.classList.remove("sticky");
  }
}

/* And my CSS: */

body {
  font-family: 'Lato', sans-serif;
  margin: 0px !important;
}

.sticky+.content {
  padding-top: 60px;
}

.sticky {
  position: fixed;
  top: 0px;
  width: 100%
}

#navbar .nav-button {
  text-align: center;
}

#navbar .nav-button a {
  width: 20%;
  float: left;
  text-transform: uppercase;
  text-decoration: none;

  -o-transition: .5s;
  -ms-transition: .5s;

  transition: .5s;
}

#navbar .nav-button a:hover {
  color: gray;

先谢谢。

Answer 1

您的#obrasky h1有position:absolute，使其重叠#icons。考虑到您当前的加价，......

#icons {
  position:relative
}

...将解决问题。

window.onscroll = function() {
  myFunction()
};

var navbar = document.getElementById("navbar");
var sticky = navbar.offsetTop;

function myFunction() {
  if (window.pageYOffset >= sticky) {
    navbar.classList.add("sticky")
  } else {
    navbar.classList.remove("sticky");
  }
}

body {
  font-family: 'Lato', sans-serif;
  margin: 0px;
}

.sticky+.content {
  padding-top: 60px;
}

.sticky {
  position: fixed;
  top: 0px;
  width: 100%
}

#navbar .nav-button {
  text-align: center;
}

#navbar .nav-button a {
  width: 20%;
  float: left;
  text-transform: uppercase;
  text-decoration: none;
  color: black;
  font-size: 20;
  transition: .5s;
}

#navbar .nav-button a:hover {
  color: gray;
}

article content #obraski img {
  margin-top: 150px;
  width: 100%;
  height: 250px;
  opacity: 0.5;
}

  font-size: 50px;
  text-align: center;
  width: 100%;
  position: absolute;

}

#icons {
  width: 100%;
}

#icons #ikonka1:hover {

}

#icons #ikonka2:hover {

}

#icons #ikonka3:hover {

}

#icons #ikonka4:hover {
  background-color: #3b5998;
}

#ikonka1,
#ikonka2,
#ikonka3,
#ikonka4 {
  margin-top: 20px;
  height: 160px;
  float: left;
  width: 25%;
  font-size: 95px;
  text-align: center;
  vertical-align: middle;
}

#icons {
  position: relative;
  cursor: pointer/* totally optional */
}

  </div>
  <div id="ikonka4">

  </div>
</div>

另一种可能的解决方法是使<h1>忽略指针事件：

#obraski h1 {
  pointer-events: none;
}

将:hover事件传递给#icons。

我无法对div应用悬停效果
