1 CSS styles for Firefox IE6 IE7
Now most are using!important to hack, for IE6 and Firefox test can be normal display, but IE7 to!important can be correctly interpreted, will cause the page did not appear as required! Find a good hack way for IE7 is to use the "*+html", now use IE7 to browse, there should be no problem.
Now write a CSS can do this:
#1 {color: #333;}/* Moz/*
* HTML #1 {color: #666}/* IE6 * *
*+html #1 {color: #999;}/* IE7 * *
Then in Firefox font color display for #333,ie6 under the font color display for #666,ie7 under the font color display as #999.
2 centering problems in CSS layouts
The main style definitions are as follows:
body {text-align:center;}
#center {Margin-right:auto; Margin-left:auto; }
Description
First, the parent element defines text-align:center, which means that the content within the parent element is centered, and for IE this setting is OK.
But you can't center in Mozilla. The solution is to add "Margin-right:auto" when the child element definition is set; Margin-left:auto; ”
What needs to be explained is that if you want to use this method to make the entire page centered, it is recommended not to be nested in a div, you can split out a number of Div, as long as in each split div defined margin-right:auto; Margin-left:auto; It's OK.
3 box models differ explained.
#box {
width:600px;
For ie6.0-w\idth:500px;
For ff+ie6.0
}
#box {
Width:600px!important
For FF
width:600px;
For ff+ie6.0
Width/**/:500px;
For ie6.0-
}
4 double distance generated by the floating IE
#box {float:left; width:100px; margin:0 0 0 100px; In this case, IE will produce 200px distance display:inline; Make floating Ignore}
Let's go over the block,inline. Two elements, the block element is characterized by: always start on a new line, height, width, row height, margin can be controlled (blocks elements); Inline element is characterized by: and other elements on the same line,... Not controllable (inline element);
#box {display:block//can simulate an inline element as a block element display:inline//effect diplay:table the same row arrangement;
5 ie with the width and height of the problem
IE does not recognize the definition of min-, but in fact it treats the normal width and height as having min. This problem is large, if only with the width and height, the normal browser in the two values will not change, if only with Min-width and min-height, ie below is not set width and height. For example, to set the background picture, this width is more important. To solve this problem, you can do this:
#box {width:80px; height:35px;} Html>body #box {width:auto; Height:auto; min-width:80px; min-height:35px;}
6 minimum width of the page
Min-width is a handy CSS command that specifies that the element should be minimal or less than a certain width, so that the layout will always be correct. But IE does not recognize this, and it actually treats the width as a minimum. To make this command available on IE, you can put a <div> under the <body> tab, and then assign a class to the DIV:
Then CSS is designed like this:
#container {
min-width:600px;
Width:expression (Document.body.clientWidth < 600?) "600px": "Auto");
}
The first min-width is normal, but the width of line 2nd uses JavaScript, which only IE recognizes, which also makes your HTML document less formal. It actually achieves the minimum width through JavaScript's judgment.
7 Clear Floating
. hackbox{
display:table;
To display an object as a table in block element level
}
Or
. hackbox{
Clear:both;
}
or add: After (Pseudo object), set in the object after the occurrence of content, usually with content with use, IE does not support this pseudo object, not IE browser support, so does not affect the Ie/win browser. This is the most troublesome
... #box: after{
Content: ".";
Display:block;
height:0;
Clear:both;
Visibility:hidden;
}
8 div Floating IE text produces 3 pixel bugs
The left side of the object floating on the right side of the outer patch to locate the left margin, the right object within the text will be left with 3px spacing.
#box {
Float:left;
width:800px;}
#left {
Float:left;
width:50%;}
#right {
width:50%;
}
*html #left {
margin-right:-3px;
That's the key.
}
HTML code
<div id=box>
<div id=left></div>
<div id=right></div>
</DIV>
9 Property Selector (This is not compatible, is a hidden CSS bug)
p[id]{}div[id]{}
p[id]{}div[id]{}
This is hidden from the IE6.0 and IE6.0 versions, and the FF and opera functions
There is a difference between the property selector and the child selector, and the scope of the child selector shrinks from the form, and the property selector is larger in scope, as in P[id], and all of the P tags have the same type of ID.
the question of IE hide-and-seek
When the div application is complex, there are some links in each column, div and so on this time is prone to hide and seek.
Some content does not show up when the mouse selects this area is found to be true on the page.
WORKAROUND: Use Line-height attribute for #layout or use fixed height and width for #layout. The page structure is as simple as possible.
11 Height not suitable
Height is not adaptable when the height of the inner object changes when the outer height can not be automatically adjusted, especially when the inner object is used
When margin or paddign. Cases:
<div id= "box" >
Content in the <p>p object </p>
</div>
Css:
#box {background-color: #eee;}
#box p {margin-top:20px;margin-bottom:20px; text-align:center;}
Workaround: Add 2 empty div object CSS code to and from the P object:. 1{height:0px;overflow:hidden;} Or add the border attribute to the Div.
