Centering the main div
I have a div and inside it is other divs.My div is:<div id="Table_01">&l开发者_如何学Ct;/div>
How can i center it so that all other divs are centered?.
margin-left: auto;
margin-right: auto;
And be sure it doesn't have a 100% width value.
-- Edit:
Since you're using a position: absolute; with a known width (of 900px in this case) you can do:
left: 50%;
margin-left: -450px;
where the -450px is half of the width, negated.
inner_div { margin:0 auto; }
To center it vertically:
inner_div { position:absolute; top:50%; margin-top:-300px; }
here is my css:
#Table_01 {
position:absolute;
left:0px;
top:0px;
width:900px;
height:600px;
}
#index-01 {
position:absolute;
background-color:#003366;
left:0px;
top:0px;
width:900px;
height:30px;
}
#index-02 {
position:absolute;
left:0px;
top:30px;
width:900px;
height:72px;
}
#index-03 {
position:absolute;
left:0px;
top:102px;
width:900px;
height:27px;
}
#index-04 {
position:absolute;
left:0px;
top:129px;
width:223px;
height:223px;
}
#index-05 {
position:absolute;
left:223px;
top:129px;
width:382px;
height:174px;
}
#index-06 {
position:absolute;
left:605px;
top:129px;
width:295px;
height:223px;
}
#index-07 {
position:absolute;
left:223px;
top:303px;
width:382px;
height:49px;
}
#index-08 {
position:absolute;
left:0px;
top:352px;
width:475px;
height:183px;
}
#index-09 {
position:absolute;
left:475px;
top:352px;
width:425px;
height:183px;
}
#index-10 {
position:absolute;
left:0px;
top:535px;
width:900px;
height:34px;
}
#index-11 {
position:absolute;
background-color:#003366;
left:0px;
top:569px;
width:900px;
height:31px;
}

should work:
Table_01 {
position:absolute;
margin-left:-300px;
left:50%;
width:900px;
height:600px;
}
This is what always works for me.
