The image element img appears with redundant blanks under IE6 _HTML/Xhtml_Web page production

When doing DIV CSS layout on the page, it is absolutely common to encounter the problem of excess white space under the image element img in IE6 (of course, sometimes in Firefox). The solution to this problem is also to "see the opportunity." "Act", different solutions should be used according to different reasons. Here we summarize the common methods to solve the BUG of excess gaps under the image layout for your reference.
1. Convert the image to a block-level object
That is, set img to: display:block;
In this example, add a set of CSS codes: #sub img {display:block;}
2. Set the vertical alignment of the image
That is, setting the vertical-align attribute of the image to "top, text-top, bottom, text-bottom" can also be solved. For example, in this example, add a set of CSS codes: #sub img {vertical-align:top;}
3. Set the text size of the parent object to 0px
That is, add a line in #sub: font-size: 0;
can solve the problem. But this also caused a new problem, the text in the parent object cannot be displayed. Even if the text part is enclosed by a sub-object, it can still be displayed by setting the sub-object text size, but an error message that the text is too small will be prompted during CSS validation.
4. Change the attributes of the parent object
If the width and height of the parent object are fixed and the image size depends on the parent object, you can set: overflow:hidden;
to solve the problem. For example, in this example, you can add the following code to #sub: width:88px;height:31px;overflow:hidden;
5. Set the floating attribute of the image
That is, add a line of CSS code in this example: #sub img {float:left;}
If you want to achieve mixed arrangement of images and text, this method is a good choice.
This method should be emphasized. In actual development, this method may cause trouble, because in order to make the code more semantic and clear when writing code, it is inevitable to provide code indentation display through the IDE, which will inevitably make the label Display in a new line with other tags, such as DW's "Apply Source Format" command. Therefore, this method can help us understand a situation where BUG occurs. The specific solution must be solved by everyone.
