字体图标及媒体查询

1. 字体图标的引入与显示

font-icon-unicode.css

@font-face {
  font-family: "iconfont"; /* Project id 3886259 */
  src: url("//at.alicdn.com/t/c/font_3886259_rduojctudo.woff2?t=1675848609007")
      format("woff2"),
    url("//at.alicdn.com/t/c/font_3886259_rduojctudo.woff?t=1675848609007")
      format("woff"),
    url("//at.alicdn.com/t/c/font_3886259_rduojctudo.ttf?t=1675848609007")
      format("truetype");
}
.dhw-font {
  font-family: iconfont;
  font-size: 5em;
  color: blue;
}

font-icon-class.css

@import url(//at.alicdn.com/t/c/font_3886259_rduojctudo.css);
.active {
  font-size: 5em;
  color: cyan;
}
.active:hover {
  font-size: 6em;
  cursor: pointer;
  opacity: 0.2;
  transition: 0.6s;
}

html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <link rel="stylesheet" href="css/icon-font-unicode.css" />
    <link rel="stylesheet" href="css/font-icon-class.css" />
    <title>字体图标</title>
  </head>
  <body>
    <!-- 1.unicode -->

      <span>&#xe635;</span>
    </div>
    <hr />

2. 媒体查询(移动优先)

<!DOCTYPE html>
<html lang="zh-CN">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>媒体查询</title>
  </head>
  <body>
    <button class="btn small">小宝</button>
    <button class="btn middle">二宝</button>
    <button class="btn large">大宝</button>
    <style>
      html {
        /* 设置1rem=10px */
        font-size: 0.625rem;
      }
      .btn {
        background-color: cyan;
        color: white;
        border: none;
        outline: none;
      }
      .btn:hover {
        cursor: pointer;
        opacity: 0.2;
        transition: 0.3s;
      }
      .btn.small {
        font-size: 1.5rem;
      }
      .btn.middle {
        font-size: 2rem;
      }
      .btn.large {
        font-size: 2.5rem;
      }
      @media (max-width: 375px) {
        html {
          font-size: 12px;
        }
      }
      @media (min-width: 375px) and (max-width: 600px) {
        html {
          font-size: 16px;
        }
      }
      @media (min-width: 600px) {
        html {
          font-size: 18px;
        }
      }
    </style>
  </body>
</html>
