书接前文，在给出了一个例子后，再给一个例子：
1.navbar
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Navbar in Flexbox</title>
<style>
*{
box-sizing: border-box;
magin:0;
padding: 0;
background-color: #242524;
}
li, a, button{
font-family: "Montserrat", sans-serif;
font-weight: 500;
font-size: 16px;
color:#edf0f1;
text-decoration: none;
}
header{
display: flex;
justify-content: flex-end;
align-items: center;
padding:30px 10%;
}
.logo{
cursor:pointer;
width:100px;
height: 30px;
}
.nav_links{
list-style: none;
}
.nav_links li{
display: inline-block;
padding: 0 20px;
}
.nav_links li a{
transition: all 0.3s ease 0s;
}
.nav_links li a:hover{
color: #0088a9;
}
button{
padding:9px 25px;
background-color: rgba(0,136,169,1);
border: none;
border-radius: 50px;
cursor:pointer;
transition: all 0.3s ease 0s;
}
button:hover{
background-color: rgba(0,136,169,0.7);
}
</style>
</head>
<body>
<header>
<img src="replacement-logos-03.jpg" alt="" class="logo">
<nav>
<ul class="nav_links">
<li><a href="">Service</a></li>
<li><a href="">Projects</a></li>
<li><a href="">About</a></li>
</ul>
</nav>
<a href="" class="cta">
<button>Clear</button>
</a>
</header>
</body>
</html>
效果如下
此时，想把logo左移，只需要修改如下：
.logo{
cursor:pointer;
width:100px;
height: 30px;
margin-right: auto;
}
效果如下：
2.通过flexbox实现浮动效果
