HTML规范说已替换和未替换的元素，但是对于我的生活来说，我不能找到替换的解释。
应该在这种情况下意味着什么。有人可以解释一下吗？

" IMG元素没有内容;它通常由src属性指定的

< http://www.w3.org/TR/CSS21/ conform.html＃被替换元素>
替换元素
CSS格式化程序仅知道内部
维度的元素。在HTML中，IMG和OBJECT元素可以替换为元素。
例如，IMG元素的内容通常被
图像替换为src。属性指定。
我想它也适用于表单小部件。

好的，所以SPAN元素显然是一个未被替换的元素<然后是
。现在，如果我要说一个带背景的*空* SPAN元素

它不是'' T。背景图像不是IMG元素，未替换的
元素的尺寸不是由用于
的图像尺寸决定的它的背景。换句话说，带有背景图像的跨度仍然不具有内在尺寸。

The HTML specs speak of "replaced" and "non-replaced" elements, yet
for the life of me I can''t find an explanation of what "replaced" is
supposed to mean in this context. Can someone explain?

"The IMG element has no content; it is usually replaced inline by the
image designated by the src attribute"
<http://www.w3.org/TR/CSS21/conform.html#replaced-element>
Replaced element
An element for which the CSS formatter knows only the intrinsic
dimensions. In HTML, IMG and OBJECT elements can be replaced elements.
For example, the content of the IMG element is often replaced by the
image that the "src" attribute designates.
I guess it also applies to form widgets.

Thanks.
OK, so a SPAN element would apparently be a non-replaced element
then. Now if I were to say an *empty* SPAN element with a background
image would then be a replaced element, what would you say?

It isn''t. A background image isn''t an IMG element, and a non-replaced
element''s dimensions aren''t dictated by the dimensions of an image used for
its background. In other words, a span with a background image still doesn''t
have intrinsic dimensions.
