                <p><strong>OVER 18 -</strong> The California DMV requires that driving students over the age of 18 pass the in-car driving test at the DMV.
                <br/><br/>Even though the DMV doesn't require driving lessons for adults, it is still a good idea to take driving lessons from a professional driving
                school. In California, driving laws are subject to change every year. Behind-the-wheel training with our certified driving instructors can keep you
                up-to-date on the latest driving laws and techniques in crash avoidance, braking, and driving safety on increasingly packed California roads.
                <br/><br/>Many adults take driving lessons to learn the latest defensive driving and safety procedures or master challenging or stressful driving
                situations, such as freeways, or busy city streets. Our patient and professional instructors can also help you gain confidence after a collision or
                behind-the-wheel scare.</p>

我是 HTML 和 CSS 的新手。

我在 13 英寸 MBA 上制作了我的第一个学校元素最终网站，当它在我的 40 英寸三星电视上显示时，元素正在移动。

目前，我将所有元素分开放置在 2 个容器中，并将它们全部定位为“绝对”。然而，当切换到三星电视时，两个容器都会向上移动(容器内的内容保持在同一位置)。

注意:我也将容器宽度设置为 100% 并保留为零。我应该用 % 而不是 px 来表示高度吗？

任何指针都会有帮助

谢谢。

您正在寻找的是创建“响应式”页面。 Bootstrap 是一种将响应式功能引入网页的绝佳且相对简单的方法。在这里查看:http://getbootstrap.com/2.3.2/
