8.8 优化前端

本章的后端逻辑代码到这里就结束了,现在的前端页面不难看,但是也不好看,由于我们是要打造一款类似微博功能的网站,恰好今日看到 twitter 更新了 UI,布局简洁值得模仿,由下图为例,我们尽可能的还原 twitter。

整体布局

由于上图中的布局呈 左-中-右 的形式,所以我们需要把默认布局更改为三栏。 resources\views\_layout\default.blade.php

...
<body>
<div class="container mt-5">
<div class="row">
<div class="col">
@include('_layout.header')
</div>
<div class="col-6">
<ul class="list-group">
<li class="list-group-item">
<a onclick="window.history.go(-1); return false;" class="btn btn-light" aria-label="Previous">
<span aria-hidden="true">&laquo;</span>
</a>
@yield('title')
</li>
<li class="list-group-item">
@yield('content')
</li>
</ul>
</div>
<div class="col">
@include('_layout.footer')
</div>
</div>
</div>
...

修改侧栏布局 resources\views\_layout\header.blade.php

<header>
<nav class="nav flex-column">
<ul class="list-group list-group-flush">
<li class="list-group-item list-group-item-action">
<a class="nav-link" href="{{ url('welcome/index/home') }}">
主页
</a>
</li>
<li class="list-group-item list-group-item-action">
<a class="nav-link" href="{{ url('user/auth/index') }}">
所有用户
</a>
</li>
@if(session('user'))
<li class="list-group-item list-group-item-action">
<a class="nav-link" href="{{ url('user/auth/index') }}">
个人资料
</a>
</li>
<li class="list-group-item list-group-item-action">
<div class="dropdown">
<a class="nav-link dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" href="">更多</a>
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<a class="dropdown-item">
<form action="{{ url('user/session/delete', ['id' => session('user.id')]) }}" method="POST">
@php echo token() @endphp
<button class="btn btn-block" type="submit" name="button">退出</button>
</form>
</a>
</div>
</div>
</li>
@else
<a class="btn btn-outline-success my-2 my-sm-0" href="{{ url('user/auth/create') }}">
注册
</a>
<a class="btn btn-outline-success my-2 my-sm-0" href="{{ url('user/session/create') }}">
登录
</a>
@endif
</ul>
</nav>
</header>

创建样式表文件 public\static\css\app.css

.pagination li:first-child {
margin-left: 0;
border-top-left-radius: 0.25rem;
border-bottom-left-radius: 0.25rem;
}
.pagination li {
position: relative;
display: block;
padding: 0.5rem 0.75rem;
margin-left: -1px;
line-height: 1.25;
color: #007bff;
background-color: #fff;
border: 1px solid #dee2e6;
}

全部保存后,刷新页面,可以看到整体的布局已经非常接近了,细节方面存在瑕疵,我们将会在后面的章节中持续优化。
