css - Iphone 5 的标题 CSS

问题描述

我想为 iPhone 5 调整我的屏幕

在此处输入图像描述

iPhone 5 的尺寸为320x568

我的问题是元素不在一条线上。

我必须减小字体大小？问题是屏幕不够小。

在此处输入图像描述

@media only screen and (max-width: 374px) and (min-width: 320px) {
    /* Iphone 5 */ 
 
    .top-bar {
        position: relative;
        height: 45px;
        background-color: aqua;
    }

    .container {
        display: flex;
        width: 100%;
    }
}

我目前不知道如何解决我的问题。

这是我的 HTML 和 CSS 代码：

解决方案

我喜欢在 CSS 中使用vw和%单元来进行响应式网页设计。
有一种简单的方法可以使用以下方法制作响应式字体大小vw：

.back {
  background: #e9e9e9;
  text-align: center;
  padding: 0.5vw 0;
}
.fore {
  margin: 5px;
  font-size: 2.5vw;
}
<div class="back">
  <span class="fore">Responsive.</span>
</div>

这是一个工作示例： 

body {
    margin: 0;
    padding: 0;
    font-family: 'Roboto Slab', serif;
    height: 100vh;
    width: 100vw;
}

a {
    text-decoration: none;
    transition: .3s;
    color: black;
    font-size: 1.5vw;
    margin-left: 2px;
    padding: 0;
}

ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
}

li {
    display: inline-block;
}

h1,
h2, 
h3, 
h4,
h5, 
h6 {
    margin: 0;
}

p {
    margin: 0;
}

如果浏览器/设备具有特定的宽度/高度，您可以使用名为“ @media”的 CSS 规则为元素设置样式：

p {
  color: #333;
  font-size: 2.5vw;
  font-family: Arial, Helvetica, sans-serif;
}
body {
  background-color: #f9f9f9;
}
@media only screen and (max-width: 600px) {
  body {
    background-color: #333;
  }
  p {
    color: white;
  }
}
<!DOCTYPE html>
<html>
  <body>
    <p style="text-align: center;">Resize the browser to see the effect.</p>
  </body>
</html>
