A few common classic CSS tips _ Experience Exchange

Center vertically with Line-height

line-height:24px;
With a fixed-width container and one row vertically centered, use Line-height (the height is consistent with the parent container), and more vertical centers can be seen here.

Clear Container Float

#main {
Overflow:hidden;
}
Before the issue was mentioned, more information can be seen here.

Do not leave a link wrapped

A
White-space:nowrap;
}
The above setting avoids the link wrapping, but the individual suggests that the long link will have a corresponding line (for a discussion of line breaks, see the records in the center of the circle).

Always let Firefox show scroll bars

HTML {
overflow:-moz-scrollbars-vertical;
}
More Mozilla/firefox private CSS properties can be consulted here. Requires cross-browser support, or you can use the

Body, HTML {
min-height:101%;
}
Center The Block element horizontally

margin:0 Auto;
is actually

Margin-left:auto;
Margin-right:auto;
This technique basically all the CSS textbooks will have a description, don't forget to add a width to it. can also be used under Exploer

body{
Text-align:center;
}
Then define the inner layer container

Text-align:left;
Recovery.

Hide Exploer textarea scroll bar

TEXTAREA {
Overflow:auto;
}
Exploer By default textarea will have a vertical scroll bar (don't ask me why).

Set up print paging

H2 {
Page-break-before:always;
}
The Page-break-before property enables you to set pagination when a page is printed.

Delete a dashed box on a link

A:active, A:focus {
Outline:none;
}
Firefox defaults to a dotted box when the link gets focus (or when clicked), and can be deleted using the properties above.

The simplest CSS reset

* {
margin:0; padding:0
}
If you want to be "complex", refer to Yui's approach (and here). In the original message, there were users who said their views.

I have to agree with Niall Doherty, * {margin:0px; padding:0px;}
Basically means "traverse every CSS element and give it these
Attributes ". That's a very unnecessary strain on the server and
A bad semantic practice, as you had to give some elements
Padding/margin again, after stripping them.
