纯CSS3黑色气泡背景动画菜单

PetitQ 导航菜单 2022-1-05 1.25K 0 0

今天我们要来分享一款非常酷的 CSS3 动画菜单，这款 CSS3 菜单有一个很漂亮的黑色气泡背景，菜单是银白色的，和黑色的背景交织在一起更加显得有 3D 立体的视觉效果。CSS3 的运用让菜单有圆角的效果，鼠标滑过菜单时也会改变背景。下面是实现这款 CSS3 菜单的过程和源代码，一起来看看。

HTML 代码：

```
<nav>
```
```
            <ul class="fancyNav">
```

                <li id="home"><a href="#home" class="homeIcon">Home</a></li>

                <li id="news"><a href="#news">News</a></li>

                <li id="about"><a href="#about">About us</a></li>

                <li id="services"><a href="#services">Services</a></li>

                <li id="contact"><a href="#contact">Contact us</a></li>

```
            </ul>
```
```
        </nav>
```

这里我们用了 ul li 列表构造了菜单的结构，非常简单。

CSS 代码：

```
.fancyNav{
```
```
	/* Affects the UL element */
```
```
	overflow: hidden;
```
```
	display: inline-block;
```
```
}
```
```
 
```
```
.fancyNav li{
```

	/* Specifying a fallback color and we define CSS3 gradients for the major browsers: */

```
 
```
```
	background-color: #f0f0f0;
```

	background-image: -webkit-gradient(linear,left top, left bottom,from(#fefefe), color-stop(0.5,#f0f0f0), color-stop(0.51, #e6e6e6));

	background-image: -moz-linear-gradient(#fefefe 0%, #f0f0f0 50%, #e6e6e6 51%);

	background-image: -o-linear-gradient(#fefefe 0%, #f0f0f0 50%, #e6e6e6 51%);

	background-image: -ms-linear-gradient(#fefefe 0%, #f0f0f0 50%, #e6e6e6 51%);

	background-image: linear-gradient(#fefefe 0%, #f0f0f0 50%, #e6e6e6 51%);

```
 
```

	border-right: 1px solid rgba(9, 9, 9, 0.125);

```
 
```

	/* Adding a 1px inset highlight for a more polished efect: */

```
 
```

	box-shadow: 1px -1px 0 rgba(255, 255, 255, 0.6) inset;

	-moz-box-shadow: 1px -1px 0 rgba(255, 255, 255, 0.6) inset;
