html-在CSS中的相对和绝对定位，以创建特定的设计
我是 CSS 新手，我正在尝试创建一个设计。设计是在盒子的左侧有“标题”。我尝试了相对定位和绝对定位，但是我不能在没有段落覆盖的情况下将“标题”放在左侧（我尝试相对于其原始位置偏移“标题”，但是当屏幕尺寸发生变化时它超出了框）。你能帮我解决这个问题吗？

<h1>Responsive Layout</h1>

Chicken meal is rendered chicken meat that has been dried and ground up, and includes clean flesh, skin, and/or accompanying bone. But if you see a bag of dog food that proudly states it's made with “Real Chicken,” it's referring to a clean combination of chicken flesh and skin.
