我不明白为什么我缩小屏幕时字体没有减小。

我将所有CSS都设置为百分比，以便所有内容都能响应。

相反，当我缩小屏幕时，字体不会改变大小，从而弄乱了设计。

我正在24英寸显示器上构建我的投资组合站点，然后在13英寸屏幕上对其进行检查以确保它可以缩放。

            <p>An entrepenurial minded, Full Stack Developer. Whenever I'm up against a challenge that I care about, it gives me a rush. Focusing on the big picture is important to me, but I never forget the smaller details. Anything that is not challenging

              is boring, and makes me yawn.

              <br />

              <br />Currently seeking a Javascript position, using the MEAN stack, in New York City. Being rebellious, ambitious, and hard working are values that are very important to me. I want to join a company that has similar values and has goals of reaching

              ridiculous levels of success, not just modest realistic ones. I love working with a solid team.
