实现网页滑动门效果需要使用CSS的伪类和定位属性。具体步骤如下：
<div class="slider">
<a href="#" class="tab active">Tab 1</a>
<a href="#" class="tab">Tab 2</a>
<div class="slider-line"></div>
</div>.slider a {
display: inline-block;
position: relative;
z-index: 1;
padding: 10px;
background-color: #fff;
border: 1px solid #ccc;
border-bottom: none;
text-decoration: none;
color: #333;
}
.slider a.active {
background-color: #f5f5f5;
border-color: #ccc;
border-bottom-color: transparent;
color: #333;
}.slider-line {
position: absolute;
z-index: 0;
bottom: 0;
height: 3px;
background-color: #007bff;
}
.slider a:nth-child(1) ~ .slider-line {
left: 0;
width: 50%;
}
.slider a:nth-child(2) ~ .slider-line {
left: 50%;
width: 50%;
}完整的代码如下：
<div class="slider">
<a href="#" class="tab active">Tab 1</a>
<a href="#" class="tab">Tab 2</a>
<div class="slider-line"></div>
</div>.slider a {
display: inline-block;
position: relative;
z-index: 1;
padding: 10px;
background-color: #fff;
border: 1px solid #ccc;
border-bottom: none;
text-decoration: none;
color: #333;
}
.slider a.active {
background-color: #f5f5f5;
border-color: #ccc;
border-bottom-color: transparent;
color: #333;
}
.slider-line {
position: absolute;
z-index: 0;
bottom: 0;
height: 3px;
background-color: #007bff;
}
.slider a:nth-child(1) ~ .slider-line {
left: 0;
width: 50%;
}
.slider a:nth-child(2) ~ .slider-line {
left: 50%;
width: 50%;
}可以通过调整链接或按钮的样式，滑动门的样式和位置来实现不同的效果。
