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 (<divclassName={`${styles.stepMenu} ${item.success ? styles.successText : styles.defaultText} ${item.status ? styles.stepMenuActive : ''}`}>{item.success ? (<><div className={`${styles.icon} ${styles.iconSuccess}`}><img src={require(`@/assets/imgs/success.png`)} alt="" /></div></>) : (<><imgclassName={styles.icon}src={require(`@/assets/imgs/${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;}
}场景二：实现效果图
