How to echo a div class?
提问by user1636968
Not sure how to do this... I'm a bit of a php noob. I'm trying to echo the div class '.header1'
不知道如何做到这一点...林有点PHP菜鸟。我试图回应 div 类“.header1”
In my css I've given .header1 a background image and I want that to appear, but I'm not having any luck so my code must be wrong. Here it is:
在我的 css 中，我给了 .header1 一个背景图像，我希望它出现，但我没有任何运气，所以我的代码一定是错误的。这里是：
echo '<div class="header1">';
.header1 {
background: url(_images/header1.png);
What am I doing wrong? I've tried it with and without the closing div but neither have worked.
我究竟做错了什么？我已经尝试过使用和不使用关闭 div 但都没有奏效。

The div tag needs both an ending tag and content.
div 标签需要结束标签和内容。
If there is no content, you need to define it's heightand widthmanually.
如果没有内容，你需要定义它height和width手动。

Whenever I echo html in php I like to use the heredoc syntax
每当我在 php 中回显 html 我喜欢使用heredoc 语法
$div = <<<DIV
<div class="header1"></div>
DIV;
Just looks somuch better, to me, especially when your strings get more complex, i.e. quotes and stuff.
只是看起来那么好很多，对我来说，尤其是当你的字符串变得越来越复杂，即报价之类的东西。
