为什么我主页上的所有内容都溢出了正文边框？

Question

在我的主页 Kendall_Gregory.html 上，我的正文边框忽略了正文中的内容并在页面周围设置了任意边框。它会忽略页面上的每个图像及其周围的 div。相同的代码适用于其他页面，我无法弄清楚为什么会出现这种情况。

Answer 1

您的边框没有包裹图像元素的原因是图像元素是浮动的并且容器没有被清除。

任何时候浮动图像或任何其他对象时，都可以将其从 normal flow 中取出。这意味着父容器甚至不知道它的存在。

有几种方法可以解决这个问题——称为 clearfix methods。在这种情况下，我使用了 overflow 属性。将 overflow: auto 添加到容器 divs.

.no-hover {overflow: auto;}
.on-hover {overflow: auto;}

我测试了这段代码，它解决了问题。

DEMO

请记住，在使用 overflow 属性时，您可以有不同的值（auto、hidden、scroll），每个值当内容溢出容器时会有不同的效果。了解每个值的作用可以参考这篇文章：MDN - CSS Overflow Property

希望这对您有所帮助。祝你好运！
