推荐答案

根据元素的内容或上下文，自动调整

The value of said property is adjusted automatically according to the content or the context of the element.

例如，块级元素与 height：auto 将变得更高，因为它包含更多的文本。再例如，具有 margin：0 auto 的块元素将具有增加的左和右边距，直到它沿着视口的y轴居中。

For example, a block-level element with height: auto will grow taller as it contains more text. For another example, a block element with margin: 0 auto will have the left and right margins increased until it becomes centered along the y-axis of the viewport.

这取决于你赋值的属性，不同的属性根据内容和上下文的不同而有所不同。

It really depends on the property you give the value to, different properties behave differently depending on the content and context.
