# 2.加圆角

使用 CSS3 border-radius 属性，你可以给任何元素制作 "圆角"。

如果你在 border-radius 属性中只指定一个值，那么将生成 4 个 圆角。

但是，如果你要在四个角上一一指定，可以使用以下规则：

四个值: 第一个值为左上角，第二个值为右上角，第三个值为右下角，第四个值为左下角。

三个值: 第一个值为左上角, 第二个值为右上角和左下角，第三个值为右下角

两个值: 第一个值为左上角与右下角，第二个值为右上角与左下角

一个值： 四个圆角值相同

border-radius: 10px 10px 10px 10px;

border-top-left-radius     定义了左上角的弧度

border-top-right-radius     定义了右上角的弧度

border-bottom-right-radius     定义了右下角的弧度

border-bottom-left-radius     定义了左下角的弧度

# 12.display 几种常用的属性值

# 第一个：display:none;

设置元素隐藏，具体可见：display:none

# 第二个：display:block;

设置元素为块级元素，块级元素可以独占一行，可设宽高。

# 第三个：display:inline;

设置元素为行内元素，一行可有多个行内块元素，可设宽高。

# 第四个：display:inline-block

设置元素为行内块元素，既有行内元素的（一行可有多个）特性，又有块元素的（可设宽高）特性

# 第五个：display:inline-table

inline-table 得到的是，外面是“内联盒子”，里面是“table 盒子”。

# 第六个：display:table

元素会作为块级表格来显示，类似 table，表格前后带有换行符;配合 table-cell 使用可实现水平垂直居中，具体可见：水平垂直居中

# 第七个：table-row

元素会作为一个表格行显示，类似 tr;

# 第八个：table-cell

元素会作为一个表格单元格显示，类似 td 和 th。

# 第九个：display:list-item

为元素内容生成一个块型盒，随后再生成一个列表型的行内盒。 会把元素作为列表显示，要完全模仿列表的话还需要加上 list-style-position，list-style-type

# 13.省略文字

如果只显示一行，则可以使用以下方法：

overflow: hidden;
text-overflow:ellipsis;
white-space: nowrap;
1
2
3

如果需要显示多行，在需要设置的元素 style 中添加以下代码：

word-break: break-all;
text-overflow: ellipsis;
display: -[webkit](https://so.csdn.net/so/search?q=webkit&spm=1001.2101.3001.7020)-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: 2;
overflow: hidden;
1
2
3
4
5
6

只显示两行：

overflow: hidden; //超出隐藏
text-overflow: ellipsis; //超出使用省略号
display: -webkit-box;
-webkit-line-clamp: 2; //第几行
-webkit-box-orient: vertical;
width: 192px; //根据需要自定义设置
height: 60px; //根据文字高度自定义设置为两行行高

（注意：有时添加在嵌入样式中不生效，需要添加在行内样式中）

# 三.问题

# 1.link 和@import 的区别？

1、从属关系区别： link 属于 html 标签，而@import 是 css 提供的。 2、加载顺序区别： 页面被加载时，link 会同时被加载，而@import 引用的 css 会等到页面被加载完再加载。 3、兼容性区别： import 只在 IE5 以上才能识别，而 link 是 html 标签，无兼容问题。 4、dom 可操作性区别： 可以通过 JS 操作 DOM ，插入 link 标签来改变样式；由于 DOM 方法是基于文档的，无法使用@import 的方式插入样式 5、权重区别： 如果已经存在相同样式，@import 引入的这个样式将被该 CSS 文件本身的样式层叠掉，表现出 link 方式的样式权重高于@import 的权重这样的直观效果。

# 2.src 与 href 的区别？

1、href 是指向网络资源所在位置，建立和当前元素（锚点）或当前文档（链接）之间的链接，用于超链接。 2、src 是指向外部资源的位置，指向的内容将会嵌入到文档中当前标签所在位置；在请求 src 资源时会将其指向的资源下载并应用到文档内，例如 js 脚本，img 图片和 frame 等元素。当浏览器解析到该元素时，会暂停其他资源的下载和处理，直到将该资源加载、编译、执行完毕，图片和框架等元素也如此，类似于将所指向资源嵌入当前标签内。这也是为什么将 js 脚本放在底部而不是头部

# 3.CSS 基础选择器总结

选择器 作用 缺点 用法
标签选择器 可以选出所有相同的标签 不能差异化选择 p { color：red;}
类选择器 可以选出 1 个或者多个标签 可以根据需求选择 .nav { color: red; }
id 选择器 一次只能选择器 1 个标签 只能使用一次(不推荐使用) #nav {color: red;}
通配符选择器 选择所有的标签 会匹配页面所有的元素，降低页面响应速度(不推荐使用) *** {color: red;}

# 4.连接和图片

  4. 复选框（Checkbox）：用于在一组选项中选择多个选项，可以同时选中多个选项。
  5. 悬停按钮（Hover Button）：当用户将鼠标悬停在按钮上时，按钮的外观会发生变化。
  6. 图像按钮（Image Button）：使用图片或图标作为按钮的外观。
  7. 开关按钮（Switch Button）：用于切换一个状态，比如打开或关闭一个选项。
  8. 下拉按钮（Dropdown Button）：当用户点击按钮时，会弹出一个下拉菜单，用户可以从中选择一个选项。

# 4.button 的添加

以下是一些 HTML 中设置按钮样式的常用方法：

1.使用 CSS 样式表：可以通过 CSS 样式表来设置按钮的外观，例如设置按钮的背景色、字体颜色、边框等。

<style>
  button {
    background-color: #4caf50;
    border: none;
    color: white;
    padding: 10px 20px;
    text-align: center;
    text-decoration: none;
    display: inline-block;
    font-size: 16px;
    margin: 4px 2px;
    cursor: pointer;
  }
</style>

3.使用类名：可以为按钮设置一个类名，然后在 CSS 样式表中设置该类名的样式。

<style>  .my-button {
    background-color: #4CAF50;
    border: none;
    color: white;
    padding: 10px 20px;
    text-align: center;
    text-decoration: none;
    display: inline-block;
    font-size: 16px;
    margin: 4px 2px;
    cursor: pointer;
} </style>
<button class="my-button">Click me</button>
