Question

我遇到了这个问题，我认为这可能是我的编码。 A＆＃34; |＆＃34;出现在我的屏幕顶部。我在代码中找不到它。就在那里＆＃34; |＆＃34;我想插入我的一张图片。有人可以帮忙找到这个＆＃34; |＆＃34;是什么？

非常感谢你帮助我的人:)我很感激！

其实！这是一次更新！我发现了什么是错的，为什么会出现！哪里有边缘，边界和背景。一旦我摆脱了那三个，线就消失了！

感谢你们帮助我的人！

Answer 1

那是<div1>元素。

顺便说一下，这在技术上是无效的HTML。将您的CSS更改为#div1 {，将该元素的HTML更改为<div id="div1">。

Answer 2

问题在于<div1>元素。删除1。如果您想给它自己的CSS样式，请改用id。

Answer 3

你给border: 1px solid black; css div1提出了奇怪的问题“|”从技术上讲，你的HTML代码不合适。
