什么是默认display:属性:AFTER和:指定后的伪元素之前content.
难道display: inline还是display: inline-block？
无法在默认的css值列表中找到它
例:
div {
border: solid 1px black;
padding: 5px;
}
div:before {
content: "Before: Am I inline-block or inline?";
color:red;
}
div:after {
content: "After: Am I Inline-block or inline?";
color:green;
}<div>Div 1</div>
<div>Div 2</div>
<div>Div 3</div>
<div>Div 4</div>
