The content of this article is about how to fit the bottom of css? The three centering methods of CSS have certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
One day the team leader asked me to change the style of a table and ask for the bottom round. I thought it was very simple at the time, so I started writing it, but I found that it couldn't achieve the effect no matter what I did (considering browser scaling). After some thinking and discussion, I came up with three methods for the bottom game.
1. Set the parent element of the form {width: 60%; margin: 0 auto;}
The code is as follows
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<style>
*
{
padding: 0;
margin: 0;
}
.main{
width: 60%;
margin:0 auto;
}
form{
position:fixed;
bottom: 0;
width: 60%;
display: block;
}
textarea
{
width: 80%;
}
input{
width: 12%;
height: 10%;
position: relative;
bottom:24px;
}
</style>
<body>
<div >
<form id="wiselyForm" >
<textarea rows="4" cols="60" name="text" id="wbk"></textarea>
<input id="xxinput" type="submit" value="Send out"/>
</form>
</div>
</body>
</html>makes the div, The form only occupies the middle part of the page, so as long as the form is at the bottom,
fill the textarea and input=submit width with width=60% to reach the bottom.
2. text-align:center;
This is a very powerful attribute when laying out the page
*
{
padding: 0;
margin: 0;
}
.main{
width: 100%;
}
form{
position:fixed;
bottom: 0;
width: 100%;
text-align: center;
}
input{
position: relative;
bottom:24px;
}When the form width covers the entire Use text-align:center to center the screen, and then fix it to the bottom.
3. Use left:50%;margin-left:-half body;
This is a very simple and quick method
<div class="main" >
<form id="wiselyForm" >
<textarea rows="4" cols="60" name="text" id="wbk"></textarea>
<input id="xxinput" type="submit" value="Send out"/>
</form>
</div>css:
*{
padding: 0 ;
margin:0;
}
form{
position: fixed;
bottom: 0;
left: 50%;/*相对于可视区窗口，距离窗口左边50%个可视区窗口*/
margin-left:-237px ;/*表格左边距离浏览器左边50%，向左偏移一半的身位表格即可居中*/
}No matter how much the window is zoomed in or out, the table will be centered. The key point is margin-left= - half of the table px
