如何使下拉菜单标题看起来更独特

Question

我可以知道如何在下拉标题之间留出差距吗？我尝试添加border:1px solid black;但它很丑陋。我希望让它像home | about | portfolio | blog | contact而不是home about portfolio blog contact.

您可以在下面尝试使用这个 css，您可以在其中将左边框添加到主<li>，将下边框添加到其子检查下面更新的 CSS 它可能会对您有所帮助。

body {

Answer 2

您可以使用白色下边框和-webkit-transiton: opacity 0.2s;，正如 freestock.tk 的评论中正确建议的那样

body {
  font-family: 'Lucida Grande', 'Helvetica Neue', Helvetica, Arial, sans-serif;
  padding: 20px 50px 150px;
  font-size: 13px;
  text-align: center;
  background: #E3CAA1;
}
ul {
  text-align: left;
  display: inline;
  margin: 0;
  padding: 15px 4px 17px 0;
  list-style: none;
  -webkit-box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
  -moz-box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
  box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
}
ul li {
  font: bold 12px/18px sans-serif;
  display: inline-block;
  margin-right: -4px;
  position: relative;
  padding: 15px 20px;
  background: #fff;
  color:#2A0851;
  cursor: pointer;
  -webkit-transition: all 0.2s;
  -moz-transition: all 0.2s;
  -ms-transition: all 0.2s;
  -o-transition: all 0.2s;
  transition: all 0.2s;
   background: -webkit-linear-gradient(white, grey); /* For Safari 5.1 to 6.0 */
    background: -o-linear-gradient(white, grey); /* For Opera 11.1 to 12.0 */
    background: -moz-linear-gradient(white, grey); /* For Firefox 3.6 to 15 */
    background: linear-gradient(white, grey); /* Standard syntax (must be last) */
}
ul li:hover {
  background: #555;
  color: #fff;
}
ul li ul {
  padding: 0;
  position: absolute;
  top: 48px;
  left: 0;
  width: 150px;
  -webkit-box-shadow: none;
  -moz-box-shadow: none;
  box-shadow: none;
  display: none;
  opacity: 0;
  visibility: hidden;
  -webkit-transiton: opacity 0.2s;
  -moz-transition: opacity 0.2s;
  -ms-transition: opacity 0.2s;
  -o-transition: opacity 0.2s;
  -transition: opacity 0.2s;  
}
ul li ul li { 
  background: #555; 
  display: block; 
  color: #fff;
  text-shadow: 0 -1px 0 #000;
}
ul li ul li:hover { background: #666; }
ul li:hover ul {
  display: block;
  opacity: 1;
  visibility: visible;
}
.bottom-separator{
  border-bottom:solid 1px white;
  -webkit-transiton: opacity 0.2s;
}
.title-separator-1{
  border-right:solid 1px #555;
}
.title-separator-2{
  border-right:solid 1.5px #555;
}

<div>
<ul><li class="title-separator-1">Home</li>
  <li class="title-separator-2">About</li>
  <li class="title-separator-2">
    Portfolio
    <ul>

Answer 3

如果你想要一些分隔符，你可以在左边或右边放置一个边框，并使用first-child或last-child伪选择器分别消除最后一个/第一个。

body {
  font-family: 'Lucida Grande', 'Helvetica Neue', Helvetica, Arial, sans-serif;
  padding: 20px 50px 150px;
  font-size: 13px;
  text-align: center;
  background: #E3CAA1;
}
ul {
  text-align: left;
  display: inline;
  margin: 0;
  padding: 15px 4px 17px 0;
  list-style: none;
  -webkit-box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
  -moz-box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
  box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
}
ul li {
  font: bold 12px/18px sans-serif;
  display: inline-block;
  margin-right: -4px;
  position: relative;
  padding: 15px 20px;
  background: #fff;
  color: #2A0851;
  cursor: pointer;
  -webkit-transition: all 0.2s;
  -moz-transition: all 0.2s;
  -ms-transition: all 0.2s;
  -o-transition: all 0.2s;
  transition: all 0.2s;
  background: -webkit-linear-gradient(white, grey);
  /* For Safari 5.1 to 6.0 */
  background: -o-linear-gradient(white, grey);
  /* For Opera 11.1 to 12.0 */
  background: -moz-linear-gradient(white, grey);
  /* For Firefox 3.6 to 15 */
  background: linear-gradient(white, grey);
  /* Standard syntax (must be last) */
  border-left: 1px solid #999;
}
ul li:first-child {
  border-left: none;
}
ul li:hover {
  background: #555;
  color: #fff;
}
ul li ul {
  padding: 0;
  position: absolute;
  top: 48px;
  left: 0;
  width: 150px;
  -webkit-box-shadow: none;
  -moz-box-shadow: none;
  box-shadow: none;
  display: none;
  opacity: 0;
  visibility: hidden;
  -webkit-transiton: opacity 0.2s;
  -moz-transition: opacity 0.2s;
  -ms-transition: opacity 0.2s;
  -o-transition: opacity 0.2s;
  -transition: opacity 0.2s;
}
ul li ul li {
  background: #555;
  display: block;
  color: #fff;
  text-shadow: 0 -1px 0 #000;
}
ul li ul li:hover {
  background: #666;
}
ul li:hover ul {
  display: block;
  opacity: 1;
  visibility: visible;
}
.bottom-separator {
  border-bottom: solid 1px white;
  -webkit-transiton: opacity 0.2s;
}

<div>
  <ul>
    <li>Home</li>
    <li>About</li>
    <li>
      Portfolio
      <ul>
        <li class="bottom-separator">Web Design</li>
        <li class="bottom-separator">Web Development</li>
        <li class="bottom-separator">Illustrations</li>
      </ul>
    </li>
    <li>Blog</li>
    <li>Contact</li>
  </ul>
</div>

Answer 4

在你的

风格中添加跟随CSS

div > ul > li:nth-child(even){
    background: black;
    width: 1px;
    margin: 0;
    padding: 0;
    height: 35px;
    top: 15px;
    z-index: 3;
 }
div > ul > li:nth-child(odd) {
    margin-left: -5px;
}

然后更新您的 html：

<div>
 <ul>
     <li>Home</li>
     <li></li>
     <li>About</li>
     <li></li>
     <li>Portfolio</li>
     <li></li>
     <ul>
      <li class="bottom-separator">Web Design</li>
      <li class="bottom-separator">Web Development</li>
      <li class="bottom-separator">Illustrations</li>
     </ul>
     <li></li>
     <li>Blog</li>
     <li></li>
     <li>Contact</li>
  </ul>
</div>
