JSP页面显示问题
JSP小白一枚，请教各位大神如下所示的页面中为什么会有那个小箭头？
程序代码：<%@ page language="java" import="java.util.*,model.Entt, model.entts.*" pageEncoding="utf-8"%>
<%@ taglib uri="/WEB-INF/tld/page.tld" prefix="p"%>
<%@ taglib prefix="c" uri="http://java. taglib prefix="fn" uri="http://java. taglib prefix="fmt" uri="http://java. HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
