我的页面如下：为什么我Thymeleaf的模板不使用布局
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.springframework.org/security/tags"
xmlns:layout="http://www.ultraq.net/thymeleaf/layout"
layout:decorate="~{layout}">
<head>
</head>
<body>
<div layout:fragment="content">
<div th:with="rowW='row col-md-9',userNameW='col-md-1',deviceIdW='col-md-4',timestampW='col-md-4',reasonW='col-md-2'">
<div><span th:text="'function='+${function}"></span></div>
<div th:unless="${function} != null and ${function} == 'save'">
<div class="col-md-3 btn btn-primary" th:classappend="rowW"><a href="localhost:8080/server-admin/card/new" class="btn-primary">New Card</a></div>
</div>
<div th:if="${function} != null and ${function} == 'save'">
<div class="col-md-3 btn btn-primary" th:classappend="rowW"><a href="localhost:8080/server-admin/card/new" class="btn-primary">New Card</a></div>
</div>
</div>
</div>
</body>
</html>
If function is null, the layout is displayed. If function is card the layout is not displayed:
For function=null:

以下是diff文件输出：
$ diff thymeleaf*

它看起来像故障不是在Thymeleaf而是Chrome浏览器。有没有人有任何想法如何继续？
我已经尝试了一些东西，但据我所知，实际HTML中的唯一区别是空白行。
在Firefox上工作原理相同。嗯 – AixNPanes
