Question

我正在创建一个网站，并且试图使页脚始终位于底部。我希望它使页脚始终位于浏览器窗口的底部，但是如果内容足够长，它将使页脚不可见并移至底部。现在，页脚始终始终位于其上方的内容之后。

我尝试设置<footer className='footer'> <div className='icons'> <span><a href='/'><img src={LinkedIn} alt='LinkedIn'/></a></span> <span><a href='/'><img src={Mail} alt='Email' /></a></span> <span><a href='/'><img src={Resume} alt='Resume' /></a></span> </div> <div> <span className='footer-link'><a href='/'>Home</a></span> <span className='footer-link'><a href='/about'>About</a></span> <span className='footer-link'><a href='/blog'>Blog</a></span> <span className='footer-link'><a href='/contact'>Contact</a></span> </div> <div className='footer-copyright'>2020 Daniel Zhang. This site was made by Daniel Zhang from scratch with React.</div> </footer>，但是没有用。我还试图避免设置固定高度。

Answer 1

尝试import datascience as ds。

flex-direction: column;

document.getElementById('add').addEventListener('click', e => {
  document.getElementById('content').innerHTML += '<br />content<br />content<br />content';
});

html,
body {
  margin: 0;
  height: 100%;
}

body {
  display: flex;
  flex-direction: column;
}

.content {
  flex: 1 0 auto;
}

.footer {
  background: #999;
  flex-shrink: 0;
}

Answer 2

您可以使用属性位置：固定；

data

Answer 3

您可以使用引导程序，并在下面使用此类。

<div className="fixed-bottom">

Answer 4

请尝试使用此代码。

body{
padding-bottom:50px; //same to the height of footer to avoid overlapping with fixed element
}

.footer {
    position: fixed;
    bottom: 0;
    left: 0;
    width: 100%;
    height:50px; //set height as per your requirement
    z-index:10;
    overflow:hidden;
}
