书接上回
上一次在文章中，我们讲解了Vue前端的容器搭建，在本文中，我们将继续细化设计，逐步完成一个较为完善的导航栏。
组件引用
组件引用是为了在较大规模开发时避免代码塞在一个文件里边，增加可读性。
在引用的主文件里的 js部分import,然后直接在 tmplate部分调用即可，代码如下
<template><div><navigator></navigator></div>
</template><style scoped></style><script setup>
// 导入组件
import navigator from "@/page/navigator/navigator.vue"
</script>
在需要被调用的组件中，记得一定要有<script setup>部分
<template><div class="navigator"></div>
</template><style scoped></style><script setup></script>
调试浏览器，发现调用成功
导航栏框架搭建
这里提供一个简单的导航栏框架设计，本文将详细讲解微调过程。
先展示初版效果：
提几个要点:
- 导航栏可以做个下端阴影，这样就算全白也会有区分度，看起来比较舒服
- 搜索框的border可以粗一点弄成圆的，用的element-plus组件所以需要使用::deep贯穿
<template><div class="navigator"><div class="logo"><img src="../../asset/board/logo.png" style="height:400%;margin-top: -21%;margin-left: 15%;user-select: none;"></div><div class="search"><el-inputv-model="keyword"placeholder="请输入搜索内容"suffix-icon="Search"class="round-input"style="width:100%; height:60%; margin-top:3%"></el-input></div><div class="selectionSet"><el-tabs v-model="activeName" class="demo-tabs" @tab-click="handleClick" style="margin-top: 3%;margin-left: 10%"><el-tab-pane label="首页" name="first"> </el-tab-pane><el-tab-pane label="资料库" name="second"> </el-tab-pane><el-tab-pane label="讨论区" name="third"> </el-tab-pane><el-tab-pane label="收藏夹" name="fourth"> </el-tab-pane></el-tabs><img src="../../asset/board/碳治郎1.png"style="height:90%;margin-left: 10%;margin-top: 0.5%"></div></div>
</template><style scoped>
.navigator {display: flex;align-items: center;/* background-color: #d5e4f4;*/background-color: #ffffff;height: 9%;/* 添加底部阴影效果 */box-shadow: 0 4px 6px -1px rgba(0, 0, 0, 0.1), 0 2px 4px -1px rgba(0, 0, 0, 0.06);
}.logo {width: 30%;height: 100%;display: flex;padding-left: 3%;
}.search {display: flex;width: 30%;height: 100%;
}:deep(.round-input .el-input__wrapper) {border-radius: 20px !important;background-color: #FFFFFF;box-shadow: 0 0 0 1.5px rgb(210, 203, 241) !important;
}.selectionSet {display: flex;width: 40%;height: 100%;
}:deep(.el-tabs__item) {color: #000000;font-size: 25px;transition: color 0.3s ease;
}::v-deep .el-tabs__active-bar {background-color: #064fe1 !important;
}:deep(.el-tabs__nav-wrap::after) {position: static !important;
}
</style><script setup>
import { ref } from 'vue';const keyword = ref('');
const activeName = ref('first');const handleClick = (tab) => {console.log(' 当前选中标签:', tab.name);
};
</script>
图片文字取消点击光标闪烁
比如点击右上tab，发现光标是闪烁的，看的很不舒服，这里可以内联为元素设置一下
之后就不可选中了,图像貌似不可以这样解决，可以给图像设计一个点击跳转或点击放大，就不会出现光标闪烁了
user-select: none
输入框偏斜
如题所示，解决方案为在外边包的div上设置user-select:none ；这个偏斜实际上是选中了这个div
输入框悬停和聚焦流光动画
以下展示为全代码，方便CV
