Remove "whitespace" between div element
This is my HTML code
<div id="div1">
<div></div><div></div><div></div><br/><div></div><div></div><div></div>
</div>
My CSS:
#div1 {
width:150px;height:100px;white-space:nowrap;
border:blue 1px solid;padding:5px;
}
#div1 div {
width:30px;height:30px;
border:blue 1px solid;
display:inline-block;
*display:inline;zoom:1;
margin:0px;outline:none;
}
If I insert the <!DOCTYPE html> before the <html> tag, the page will look like this:
But if I remove the <!DOCTYPE html> tag, the 'whitespace' between the two lines will be remove
But I'd like to use <!DOCTYPE html> tag, it's recommend, but I can't find any CSS rule that can remove that whitespace, I have used margin:0;outline:none; etc... but it not work , anyone help me. Thanks!( I'm not good at English ...)
Answer
The cleanest way to fix this is to apply the vertical-align: top property to you CSS rules:
#div1 div {
width:30px;height:30px;
border:blue 1px solid;
display:inline-block;
*display:inline;zoom:1;
margin:0px;outline:none;
vertical-align: top;
}
If you were to add content to your div's, then using either line-height: 0 or font-size: 0 would cause problems with your text layout.

Where This Problem Comes From
This problem can arise when a browser is in "quirks" mode. In this example, changing the doctype from:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
to
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Strict//EN">
will change how the browser deals with extra whitespace.
In quirks mode, the whitespace is ignored, but preserved in strict mode.
