解决行内元素、行内块元素产生水平空隙

问题:行内元素和行内块元素之间换行的话,即使除去内外边距,他们之间还是会有距离,如下:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .span-wrap span,.span-wrap input{
            padding: 0;
            margin: 0;
        }
    </style>
<body>
<div class="span-wrap">
    <span>行内元素</span>
    <span>行内元素</span>
    <input type="text" value="行内块元素">
</body>
</html>

解决方法:

1.代码内删除行内元素、行内块元素之间的换行符、tab(制表符)、空格等字符

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .span-wrap span,.span-wrap input{
            padding: 0;
            margin: 0;
        }
    </style>
<body>
<div class="span-wrap">
    <span>行内元素</span><span>行内元素</span><input type="text" value="行内块元素">
</body>
</html>

不推荐,影响阅读
2. 利用HTML注释

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .span-wrap span,.span-wrap input{
            padding: 0;
            margin: 0;
        }
    </style>
<body>
<div class="span-wrap">
    <span>行内元素</span><!--
    --><span>行内元素</span><!--
    --><input type="text" value="行内块元素">
</body>
</html>

 

不推荐,写起来费时,影响结构
3. 为父元素设置设置font-size:0
注意子元素要重新设置font-size      

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .span-wrap{
            font-size: 0;
        }
        span,input{
            padding: 0;
            margin: 0;
            font-size: 12px;
        }
    </style>
<body>
<div class="span-wrap">
    <span>行内元素</span>
    <span>行内元素</span>
   <input type="text" value="行内块元素">
</body>
</html>

4.利用浮动
利用浮动的元素是紧挨的这一特性

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        span,input{
            padding: 0;
            margin: 0;
            float: left;
        }
    </style>
<body>
<div class="span-wrap">
    <span>行内元素</span>
    <span>行内元素</span>
   <input type="text" value="行内块元素">
</body>
</html>
