div没有显示在javascript中？

Question

I'm doing the odin project and for the front-end webdev project, I have to create a grid using javascript/jQuery. 我正在做odin项目，对于前端webdev项目，我必须使用javascript / jQuery创建一个网格。 I tried using the createElement method but I was wondering how I would be able to make the div visible in html? 我尝试使用createElement方法，但我想知道如何在html中显示div？ Am I going about this all wrong? 我要解决所有这些错误吗？

HTML: HTML：

<!DOCTYPE html>
    <html>

    <head>
        <title>Etch-a-Sketch</title>
        <link rel="stylesheet" type="text/css" href="etch-a-sketch.css">

        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

        <script type = "text/javascript" src="etch-a-sketch.js"></script>

    </head>

    <body>


    </body>

</html>

JS: JS：

var div = document.createElement("div");
div.style.width = "100px";
div.style.height = "100px";
div.style.color = "blue";

document.body.appendChild(div);

Answer 1

Add background-color 添加background-color

var div = document.createElement("div");
div.style.width = "100px";
div.style.height = "100px";
div.style.color = "blue";

div.style.backgroundColor = "yellow";//you forgot background color

document.body.appendChild(div);

Answer 2

Add more styling to make it visible, such as a border or background color. 添加更多样式以使其可见，例如边框或背景色。

 var div = document.createElement("div"); div.style.width = "100px"; div.style.height = "100px"; div.style.color = "blue"; div.style.backgroundColor = "blue"; document.body.appendChild(div);
