我正在尝试使我的标题横幅拉伸/适合网站的尺寸，但是，我不确定如何在每个浏览器上实现这一点。

HTML5：

<!doctype html>
<html lang="en">

    <head>
        <meta charset="utf-8" />
        <title>Play - Learn - Grow</title>
        <link rel="stylesheet" href="main.css">
    </head>

    <body class="body">

        <span class="text_h">
        Welcome to KUBE Toy Library!
        </span>

        <span class="banner_h">
            <img src="Images\Top_Banner.jpg" alt="Banner" height="150" width ="1240"/>
        </span>

        <nav>
            <ul class="nav">
                <li><a href="index.html">Home</a></li>
                <li><a href="about.html">About Us</a></li>

            </ul>
        </nav>

        <span class="banner_l">
            <img src="Images\Left_Banner.jpg" alt="Banner" />
        </span>

        <span class="banner_r">

        </span>

尝试：

* {margin:0; padding: 0;}
.banner_h {display: block; width: 100%;}
.banner_h img {width:100%}

在小提琴中检查结果。
