CSS:导航栏三角箭头
用CSS实现导航流程图的样式。可根据自己的需求进行修改，代码精略的写了一下。
注：场景一和场景二在分辨率比较低的情况下会有一个1px的缝隙不太优雅，自行处理。有个方法是直接在每个外面包一个DIV，用动态样式设置底色。
场景一、实现效果图的导航栏
代码部分：
/** 组件：步骤条样式 */
const StepModel = (list: any) => {
return (
<>
<div className={styles.step}>
{list.map((item: any) => {
return (
<div
className={`${styles.stepMenu} ${
item.success ? styles.successText : styles.defaultText
} ${item.status ? styles.stepMenuActive : ''}`}
>
{item.success ? (
<>
<div className={`${styles.icon} ${styles.iconSuccess}`}>
<img src={require(`@/assets/imgs/success.png`)} alt="" />
</div>
</>
) : (
<>
<img
className={styles.icon}
src={require(`@/assets/imgs/${
item.activeIcon ? item.activeIcon : item.icon
}.png`)}
alt=""
/>
</>
)}
{item.name}
</div>
);
})}
</div>
</>
);
};
/** 组件样式 */
.step {
width: 100%;
height: 32px;
margin-top: 8px;
font-size: 12px;
font-weight: 400;
display: flex;
justify-content: space-between;
filter: drop-shadow(-1px 1px 9px rgba(8, 38, 55, 0.1));
.successText {
color: #222222;
}
.defaultText {
color: #788295;
}
.stepMenu {
padding: 0px 10px 0 30px;
line-height: 32px;
background: white;
display: flex;
align-items: center;
position: relative;
flex-basis: calc((100%) / 5);
.icon {
width: 16px;
height: 16px;
margin-right: 8px;
}
.iconSuccess {
background: #00b864;
border-radius: 50%;
display: flex;
align-items: center;
justify-content: center;
}
}
/** 箭头样式 */
.stepMenu:after {
content: '';
display: block;
position: absolute;
right: -11px;
top: 5px;
z-index: 10;
border-left: 15px solid white;
border-top: 7px solid white;
border-right: 7px solid transparent;
border-bottom: 15px solid transparent;
transform: rotate(135deg);
border-top-left-radius: 6px;
filter: drop-shadow(-3px -4px 2px rgba(8, 38, 55, 0.1));
}
/** 选中样式 */
.stepMenuActive {
color: #fff;
background: linear-gradient(to right, #60c9fc, #296be8);
font-weight: 700;
}
/** 选中样式：箭头 */
.stepMenuActive:after {
border-left: 16px solid #296be8;
border-top: 7px solid #296be8;
border-right: 7px solid transparent;
border-bottom: 16px solid transparent;
}
/** first 样式加圆角 */
.stepMenu:first-child {
border-radius: 4px 0 0 4px;
padding-left: 18px;
}
/** last 样式加圆角 */
.stepMenu:last-child {
border-radius: 0px 4px 4px 0px;
padding-right: 18px;
}
.stepMenu:last-child:after {
display: none;
}
