大家好，
如果您在浏览器上查看我的网站，则向下滚动“ h1”时会看到“我的技能”位于下一页开始之前。
https://codepen.io/JamesMcGill/pen/KGNEWd在Codepen上，甚至更糟。
我很难弄清楚为什么会这样。
好吧，从技术上讲，它不在同一页面上。但是，它的确与欢迎页面上的内容出现在相同的背景图像中。
请给我一些有关如何解决此问题的建议。
谢谢..
最佳答案
您已将背景图像应用于body元素，这将使其充满整个屏幕。如果只希望它覆盖第一部分，则应将背景图像规则应用于该特定部分。
它在底部加倍，因为background-repeat: repeat是默认值，并且您尚未声明替代方法。如果要填充整个屏幕，可以添加background-size: cover，或直接添加background-repeat: no-repeat以防止出现两倍。
