Question

我正在尝试创建一个具有页脚菜单的网站。我在内容中使用container，因为我不知道如何使其居中。当我尝试应用页脚菜单而不使用container时。页脚的background-color向上扩展，最后一个div没有容器。而且文字不会居中。

Sample

当我使用.mainbar:float:left;和.sidebar:float:right;时会变成这样

HTML

    <div class="container" id="content">
      <div class="mainbar">
         <img src="img/img2.png"><br>
            <h4>Sample text.</h4>
      </div>
      <div class="sidebar">
         <a href="#"><img src="img/banner.png"></a><br>
         <a href="#"><img src="img/banner.png"></a>
      </div>
    </div>


<footer>
        <div id="fnav"">
            <ul>
                <li class="fmenu-item"><a href="#">HOME</a></li>
                <li class="fmenu-item"><a href="#">会社情報</a></li>
                <li class="fmenu-item"><a href="#">製品情報</a></li>
                <li class="fmenu-item"><a href="#">採用情報</a></li>
                <li class="fmenu-item"><a href="#">お知らせ</a></li>
                <li class="fmenu-item"><a href="#">サポート</a></li>
                <li class="fmenu-item"><a href="#">お問い合わせ</a></li>
            </ul>
        </div>
        <div class="copyright">
                COPYRIGHT © SAMPLE Template .ALL RIGHTS RESERVED.
        </div>
        </div>
</footer>

CSS

#content .mainbar{
            float: left;
            width: 736px;
}
.sidebar{
        float: right;
        width: 214px;
}
#fnav{

    text-align: center;

    list-style: none;
    margin: auto;
    width: 1000px;
 }    
 #fnav ul li.fmenu-item {
    flex-grow: 1;
    padding: 10px 0 10px 0;
}    
#fnav ul li.fmenu-item a{
    color: #262d33;
    text-decoration: none;
}    
.copyright{
    font-size:10px;
    color:#444;
    text-align:center;
    position: relative;
    margin-bottom: 10px;
    letter-spacing: 0.1em;
}

Answer 1

也应用此样式，可以解决您的问题。

footer {
   float: left;
   width: 100%;
}

Answer 2

希望这可以帮助您footer风格

footer {
    float: right;
    width: 100%;
    }

Answer 3

如果您使用的是Bootstrap 4，则无需使用Float。请检查以下示例，它可能会对您有所帮助。

.content-bar {
  min-height: 450px;
  background: #ddd;
}
.side-bar {
  min-height: 450px;
  background: #eee; 
}
footer {
  background: #ccc;
  margin-top: 15px;
}
