Yes it will. You can help yourself by using the w3's validatordirect input option:
是的，它会。您可以使用w3 的验证器直接输入选项来帮助自己：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">

Absolutely.
绝对地。
Here's the definition from an XHTML-strict DOCTYPE for a span element.
下面是一个 XHTML 严格的 DOCTYPE 对 span 元素的定义。
<!ELEMENT span %Inline;> <!-- generic language/style container -->
<!ATTLIST span
%attrs;
>
The "%Inline" part tells me that it can have child nodes from the "% Inline;" entities element list.
"%Inline" 部分告诉我它可以有来自 "% Inline;" 的子节点。实体元素列表。
The span element is included in the list of elements classed as "% Inline", that combined with span allowing "%Inline" child elements tells me that span is a valid child of span.
span 元素包含在归类为“% Inline”的元素列表中，结合 span 允许“%Inline”子元素告诉我 span 是 span 的有效子元素。
回答by dusoft
SPAN can contain only inline elements, such as SPAN etc.
SPAN 只能包含内联元素，例如 SPAN 等。
