Div Dislocation/Resolve IE6, IE7, IE8 style incompatibility issues

IE6 Div Dislocation problem Original: Chinafine

The use of "Float:left" div in IE8, IE7, there is no problem, IE6 down, there is a blank. This is because the kernel used by the IE6 by default adds the distance between the div to three px, so try to add "margin-left:-5px" to the style of the lower Div. or smaller.
Resolve IE7, IE8 style incompatibility issues

Method One, to add the following HTTP Meta-tag to the page:
<meta http-equiv= "x-ua-compatible" content= "Ie=emulateie7"/>

As soon as IE8 read this tag, it will automatically start the IE7 compatibility mode to ensure the full display of the page.

Method Two, for the entire Web site, add the following descriptor in IIS can have the same effect, of course, the scope is wider.

<?xml version= "1.0" encoding= "Utf-8"?>
<configuration>
<system.webServer>
<customHeaders>
<add name= "x-ua-compatible" value= "Ie=emulateie7" >
</customHeaders>
</system.webServer>
</configuration>

Resolve IE6, IE7, IE8 style incompatibility issues

Now we always have to consider some compatibility issues between browsers when we do Web pages. Recently in the project of making a short message platform. In the project development process let me encounter a headache is IE7 and IE8 incompatible. There are many ways to solve the problem. Now shared as follows:

If your page is IE7 compatible, and you don't want to make a lot of changes to your existing code, and you can use it in IE8, Microsoft claims that developers just need to add a line of code to the current IE7-compatible site to solve the problem, as follows:

Fix CSS style compatibility issues with Firefox IE6 IE7

Do theme The most troublesome is the CSS style compatibility problem, because each browser to the different interpretation of CCS, resulting in the original IE7 can be normal display, but to the Firefox, IE6 and other browsers, but there are dislocation, sinking and other problems, had to be in Firefox, IE6, IE7 between the constant switch debugging, Sweat... Recently there are two browsers joined Googlechrome and IE8, a browser eminence seems hopeless, can only try to overcome compatibility issues. Finding an article that addresses compatibility issues is still very effective.

1 CSS styles for Firefox IE6 IE7

Now most are used!important to hack, for IE6 and Firefox test can display normally, but IE7 to!important can correctly explain, will cause the page did not display as required! Find a good for IE7 hack way is to use "*+html", now with IE7 browsing, should have no problem now write a CSS can do this:

#1 {color: #333;}/* Moz */

* HTML #1 {color: #666;}/* IE6 */

*+html #1 {color: #999;}/* IE7 */

Then under Firefox font color display as #333,ie6 under the font color display as #666,ie7 under the font color display as #999.

2 centering issues in CSS layouts

The main style definitions are as follows:

body {text-align:center;}

#center {Margin-right:auto; Margin-left:auto; }

Description

The text-align:center is defined first in the parent element, which means that the content within the parent element is centered, and the setting for IE is already available.

But it can't be centered in Mozilla. The solution is to add "Margin-right:auto" when the child element is defined; Margin-left:auto; ”

It should be explained that if you want to use this method to make the whole page to center, it is recommended not to set in a Div, you can split the div in turn, as long as in each of the split Div defined margin-right:auto; Margin-left:auto; You can do it.

3 box model different interpretations.

#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 The 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}

Here Block,inline two elements, the block element is characterized by: always start on the new line, height, width, row height, the margin can be controlled (block elements), the characteristics of the inline element is: and other elements on the same line,... Uncontrollable (inline element);

#box {display:block;//can simulate a block element display:inline for inline elements;//Achieve the effect of the same row arrangement diplay:table;

5 ie with width and height issues

IE does not recognize the definition of min-, but in fact it treats the normal width and height as a condition of min. This problem is big, if only with the width and height, the normal browser of these two values will not change, if only with Min-width and min-height, ie, the following is not set width and height. For example, to set the background image, this width is more important. To solve this problem, you can:

#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 allows you to specify that the element should be minimal or less than a certain width, so that the layout is always correct. But IE doesn't recognize this, and it actually puts width as the minimum width. To make this command available on IE, put a <div> into the <body> tab and specify a class for the DIV:

Then the 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 by JavaScript's judgment.

7 Clear Float

. hackbox{

display:table;

Display an object as a block-element-level table

}

Or

. hackbox{

Clear:both;

}

or join: After (pseudo-object), set what happens after the object, usually in conjunction with content, IE does not support this pseudo-object, non-IE browser support, so does not affect the Ie/win browser. The most troublesome of these

... #box: after{

Content: ".";

Display:block;

height:0;

Clear:both;

Visibility:hidden;

}

8 div Floating IE text generates 3 pixel bug

The left object floats, the right side is positioned with the left margin of the outer patch, and the text within the right object is spaced 3px away from the left.

#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 attribute Selector (this is not compatible, is a bug to hide CSS)

p[id]{}div[id]{}

p[id]{}div[id]{}

This is hidden for IE6.0 and IE6.0 versions, and the FF and opera functions

There is a difference between the property selector and the child selector, the range of the child selector is reduced in form, the range of the property selector is larger, such as P[id], and all P tags have the same type of ID.

Ten IE hide and seek problems

When the div application is complex, there are some links in each column, and the div is prone to hide-and-seek problems.

Some content does not show up when the mouse selects this area is found content is indeed 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 adapted

Height is not adjusted when the height of the inner object changes, the outer height cannot be automatically adjusted, especially when the inner layer object uses

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 the P object:. 1{height:0px;overflow:hidden;} Or add the border attribute to the Div.

Note: IE can recognize *; standard browsers (such as FF) do not recognize *;

IE6 can recognize *, but not!important,

IE7 can recognize *, can also identify!important;

FF does not recognize *, but can identify!important;
