请开始点击按钮，您会注意到每个按钮的底部出现一个浅蓝色左右的边框。

如果您将鼠标悬停在最后一个子项（带有图标的最后一个菜单项），则无需单击即可发生这种情况。我正在使用引导框架。

为什么会这样？很奇怪。

这是我的 HTML 代码：

<header class="container">
    <div id="logo"></div>
    <br />
    <div id="menu">
        <ul id="menuitems">
            <li id="menu-active"><a href="#" >HOMEPAGE</a></li></a>
            <li><a href="#">PLAY NOW</a></li>
            <li><a href="#">COMMUNITY</a></li>
            <li><a href="#">HUNGER WIKI</a></li>
            <li><a href="#">HIGHSCORES</a></li>
            <li><a href="#">HELP</a></li>
            <li><div id="login"></div></li>
        </ul>
    </div>
</header>

这是我的 CSS 代码：

#menu { 
    background-image: url("../img/gradient-header.png");
    background-repeat: repeat;
    width: 100%;
    height: 56px;
    border: solid 1px #000;
    font-weight: bold;
}

#menuitems {
padding: 0;
margin: 0;
float: left;
}

#menuitems li {
    background-image: url("../img/gradient-header.png");
    background-repeat: repeat;  
    display: inline-block;
    width: 140px;
    height: 56px;
    float: left;
    border-right: solid 1px #44acbf;
    border-left: solid 1px #114a56;
    line-height: 56px;
    text-align: center;
    -webkit-transition: all 200ms ease-in-out;
        -moz-transition: all 200ms ease-in-out;
        -ms-transition: all 200ms ease-in-out;
        -o-transition: all 200ms ease-in-out;
        transition: all 200ms ease-in-out;      
}

#menuitems li:hover {
    background-image: url("../img/gradient-1.png");
    background-repeat: repeat;  
    border-right: solid 1px #2b6e81;
    cursor: pointer;
    -webkit-transition: all 200ms ease-in-out;
        -moz-transition: all 200ms ease-in-out;
        -ms-transition: all 200ms ease-in-out;
        -o-transition: all 200ms ease-in-out;
        transition: all 200ms ease-in-out;  
}

#menuitems li:last-child:hover {
    background-image: url("../img/gradient-menu-login-hover.png") !important;
    background-repeat: repeat;
}

#menuitems li:active {
    background-image: url("../img/gradient-onClick-menu.png");
    background-repeat: repeat;  
}

#menuitems li:last-child {
    width: 88px;
    border-right: solid 0px transparent;
}

#menu-active {
    background-image: url("../img/gradient-1.png") !important;
    background-repeat: repeat !important;   
    border-right: solid 1px #2b6e81 !important;
}

#menuitems li:first-child {
    border-left: solid 0px transparent;
}

#login {
    background-image: url("../img/icon.png");
    background-repeat: no-repeat;
    margin-left: 32%;   
    margin-top: 20%;    
    width: 25px;
    height: 21px;
}

#menuitems a {
    width: 140px;
    height: 56px;
    color: #fff;
    text-decoration: none;
    border-bottom: solid 0px transparent;
    border-top: solid 0px transparent;
}

#menuitems a:hover {
    text-decoration: none;
    border-bottom: solid 0px transparent;
    border-top: solid 0px transparent;
}

问题是什么？

尝试将您的transition-timing-functionfrom更改ease为linear.
