How to solve the problem of gaps under CSS images

This article mainly introduces 6 solutions to the problem of gaps under CSS pictures. Friends who need it can refer to it

When doing p CSS layout on the page, I encountered IE6 (of course sometimes under Firefox) You will encounter this problem occasionally) The problem of excess white space under the image element img in the browser is definitely common. The solution to this problem is also "play it by ear". Different solutions are needed depending on the reasons. Here is the solution directly to the image A summary of common methods for fixing bugs with extra gaps under the image layout is provided for your reference.

1. Convert the image to a block-level object

That is, set img to:

display: block;

Add a set of CSS codes in this example:

#sub img {display:block;}

Invalid for IE6/7

2. Set the vertical alignment of the image

It can also be solved by setting the vertical-align attribute of the image to "top, text-top, bottom, text-bottom". 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;

Okay 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, 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 image 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.
