Type

type.less主要设置了字体

1. 字体

1.1 标题

标题效果

代码

h1, h2, h3, h4, h5, h6,
.h1, .h2, .h3, .h4, .h5, .h6 {
  font-family: @headings-font-family;
  font-weight: @headings-font-weight;
  line-height: @headings-line-height;
  color: @headings-color;

  small,
  .small {
    font-weight: normal;
    line-height: 1;
    color: @headings-small-color;
  }
}

h1, .h1,
h2, .h2,
h3, .h3 {
  margin-top: @line-height-computed;
  margin-bottom: (@line-height-computed / 2);

  small,
  .small {
    font-size: 65%;
  }
}
h4, .h4,
h5, .h5,
h6, .h6 {
  margin-top: (@line-height-computed / 2);
  margin-bottom: (@line-height-computed / 2);

  small,
  .small {
    font-size: 75%;
  }
}

h1, .h1 { font-size: @font-size-h1; }
h2, .h2 { font-size: @font-size-h2; }
h3, .h3 { font-size: @font-size-h3; }
h4, .h4 { font-size: @font-size-h4; }
h5, .h5 { font-size: @font-size-h5; }
h6, .h6 { font-size: @font-size-h6; }
  1. 设置了默认的字体,字体粗细,行高,粗细
  2. margin和small在h1~h3 & h4~h6 做了不同的配置

1.2 内容字体

p {
  margin: 0 0 (@line-height-computed / 2);
}

.lead {
  margin-bottom: @line-height-computed;
  font-size: floor((@font-size-base * 1.15));
  font-weight: 300;
  line-height: 1.4;

  @media (min-width: @screen-sm-min) {
    font-size: (@font-size-base * 1.5);
  }
}
  1. p标签设置了基本的margin和h4~h6的一致

  2. .read主要味儿了提供阅读做了

    1. margin-btoom和h1~h3一致

    2. 增加了字体大小和粗细还有行间距

    3. 小分辨率下增加文字大小.

1.3 辅助性文字

  1. 普通small

     // Ex: (12px small font / 14px base font) * 100% = about 85%
 small,
 .small {
   font-size: floor((100% * @font-size-small / @font-size-base));
 }

    再看一下@font-size-small的设置

     @font-size-small: ceil((@font-size-base * 0.85)); // ~12px

    所以small一般为父元素的百分之85%~..

  2. mark字体

     mark,
 .mark {
   background-color: @state-warning-bg;
   padding: .2em;
 }
    1. 设置了背景颜色
    2. 设置了padding为字体大小了0.2倍

  3. 字体定位 & 大小写

     .text-left           { text-align: left; }
 .text-right          { text-align: right; }
 .text-center         { text-align: center; }
 .text-justify        { text-align: justify; }//两端对齐
 .text-nowrap         { white-space: nowrap; }

 // Transformation
 .text-lowercase      { text-transform: lowercase; }
 .text-uppercase      { text-transform: uppercase; }
 .text-capitalize     { text-transform: capitalize; }//首字母大写

  4. 字体颜色

    字体颜色

     .text-muted {
   color: @text-muted;
 }
 .text-primary {
   .text-emphasis-variant(@brand-primary);
 }
 .text-success {
   .text-emphasis-variant(@state-success-text);
 }
 .text-info {
   .text-emphasis-variant(@state-info-text);
 }
 .text-warning {
   .text-emphasis-variant(@state-warning-text);
 }
 .text-danger {
   .text-emphasis-variant(@state-danger-text);
 }

 .text-emphasis-variant(@color) {
   color: @color;
   a&:hover,
   a&:focus {
     color: darken(@color, 10%);
   }
 }
    1. 普通字体颜色配置
    2. primary~danger还设置了选中/焦点效果加亮.

  1. 显著展示文字

    显著文字

     .bg-primary {
   // Given the contrast here, this is the only class to have its color inverted
   // automatically.
   color: #fff;
   .bg-variant(@brand-primary);
 }
 .bg-success {
   .bg-variant(@state-success-bg);
 }
 .bg-info {
   .bg-variant(@state-info-bg);
 }
 .bg-warning {
   .bg-variant(@state-warning-bg);
 }
 .bg-danger {
   .bg-variant(@state-danger-bg);
 }

 .bg-variant(@color) {
   background-color: @color;
   a&:hover,
   a&:focus {
     background-color: darken(@color, 10%);
   }
 }

    这里和字体颜色类似,只不过换成了背景颜色

    因为默认的.bg-primart为蓝色,故字体要换成白色,黑色不明显.

2. List

  1. 有序 & 无序 列表

     ul,
 ol {
   margin-top: 0;
   margin-bottom: (@line-height-computed / 2);
   ul,
   ol {
     margin-bottom: 0;
   }
 }

    基本的间距设置

    清除基本列表图标

     .list-unstyled {
   padding-left: 0;
   list-style: none;
 }

    横排列表

     .list-inline {
       .list-unstyled();
       margin-left: -5px;

       > li {
         display: inline-block;
         padding-left: 5px;
         padding-right: 5px;
       }
     }
    1. 清除基本列表图标
    2. margin-left:-5px 为了对齐,抵消列表默认会向右5px
    3. 设置li只占据一块切可计算,设置padding

  2. 描述列表

     dl {
   margin-top: 0; // Remove browser default
   margin-bottom: @line-height-computed;
 }
 dt,
 dd {
   line-height: @line-height-base;
 }
 dt {
   font-weight: bold;
 }
 dd {
   margin-left: 0; // Undo browser default
 }

    基本样式设计.

    竖排描述

    竖排描述

     .dl-horizontal {
   dd {
     &:extend(.clearfix all); // Clear the floated `dt` if an empty `dd` is present
   }

   @media (min-width: @dl-horizontal-breakpoint) {
     dt {
       float: left;
       width: (@dl-horizontal-offset - 20);
       clear: left;
       text-align: right;
       .text-overflow();
     }
     dd {
       margin-left: @dl-horizontal-offset;
     }
   }
 }

 .text-overflow() {
   overflow: hidden;
   text-overflow: ellipsis;
   white-space: nowrap;
 }
    1. dd清除dt的浮动影响
    2. dt排列只在小屏幕下可行
    3. dt文字过多时用...隐藏多出文字,dt漂浮向右.

3 引导块

引导块

blockquote {
  padding: (@line-height-computed / 2) @line-height-computed;
  margin: 0 0 @line-height-computed;
  font-size: @blockquote-font-size;
  border-left: 5px solid @blockquote-border-color;

  p,
  ul,
  ol {
    &:last-child {
      margin-bottom: 0;
    }
  }

  // Note: Deprecated small and .small as of v3.1.0
  // Context: https://github.com/twbs/bootstrap/issues/11660
  footer,
  small,
  .small {
    display: block;
    font-size: 80%; // back to default font-size
    line-height: @line-height-base;
    color: @blockquote-small-color;

    &:before {
      content: '\2014 \00A0'; // em dash, nbsp
    }
  }
}
  1. 设置了基本的padding和margin
  2. p,'ul','ol'的最后一个子类maring-bottom为0
  3. footer等主要作标注作用,单独起一行,设置大小和行高,还有前面的-通过:before实现

.blockquote-reverse的向右设定

.blockquote-reverse,
    blockquote.pull-right {
      padding-right: 15px;
      padding-left: 0;
      border-right: 5px solid @blockquote-border-color;
      border-left: 0;
      text-align: right;

      // Account for citation
      footer,
      small,
      .small {
        &:before { content: ''; }
        &:after {
          content: '\00A0 \2014'; // nbsp, em dash
        }
      }
    }
  1. 在blockquote增加了文本向右对齐,设置了前置padding
  2. 标注改在后面,用:after设置-,前面的:before为了覆盖之前blockquote的-.

4 地址

address {
  margin-bottom: @line-height-computed;
  font-style: normal;
  line-height: @line-height-base;
}

这个基本没有作用..
