How to deal with gaps under CSS images

This time I will bring you How to deal with gaps under CSS images, what are the precautions when dealing with gaps under CSS images, the following is a practical case, let’s take a look .

When doing p+CSS typesetting 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 under Firefox). The solution to this problem is absolutely common. The method is also "play it by ear", and different solutions should be used depending on the reasons. Here, we directly summarize the common methods to solve the BUG of extra gaps under the image layout for your reference.

1. Convert the image to a block-level object

That is, set img to:

display: block;

Add a set of CSS code in this example: #sub img {display:block;}

Invalid for IE6/7

2. Set the vertical alignment of the image

That is, set the vertical-align attribute of the image to "top, text-top, bottom, text-bottom" It 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 , adding 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 properties of the parent object

If the width and height of the parent object are fixed and the image size depends on the parent object, then You can set: overflow:hidden; to solve this problem.

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

In this example, add a line of CSS code: #sub img {float:left;}

If you want to achieve mixed arrangement of images and text, this method is a good choice.

6. Cancel the space between the picture tag and the last closing tag of its parent object.

This method should be emphasized. In actual development, this method may cause trouble, because when writing code, in order to make the code more semantic and clear, it is inevitable to provide the code through the IDE. Indent display, which will inevitably cause labels and other labels to be displayed on new lines, 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.
