Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

前端切图工具库

Readme

jason

前端切图库 —— 分为定宽和响应式,需要手动选择其css

flex

优先使用flex版本做栅格 如果想使用 float 的栅格,在src/scss/variables.scss 中改变

// 是否开启弹性盒子布局
$flex: true;

定宽库 和 响应式库的区别

基本没有区别 =。= 只是定宽库要将 代表 屏幕的标示去掉 比如 row-10 mt-20

reset 说明

挪用了jason-reset 给 链接 和 按钮 增加了 默认的过度效果

a, button {
  transition: all .2s ease;
}

栅格布局系统

参考 bootstrap 。基本与bootstrap的栅格系统一致 新增了行中列间距的概念 注意:在需要栅格布局的时候,需严格按照 .container/.container-fluid > .row > .col 的栅格模式去布局

例子

<div class="container">
  <div class="row row-lg-50 row-md-30 row-sm-15 row-xs-10">
    <div class="col-xs-6"></div>
    <div class="col-xs-6"></div>
  </div>
</div>

布局工具类

例子

<div class="container">
  <div class="row row-lg-50 row-md-30 row-sm-15 row-xs-10">
    <div class="col-xs-6">
      <div class="mt-lg-50 mt-md-30 mt-sm-15 mt-xs-10">abc</div>
    </div>
    <div class="col-xs-6">
      <div class="mt-lg-50 mt-md-30 mt-sm-15 mt-xs-10">abc</div>
    </div>
  </div>
</div>
  • m代表margin
  • p代表padding
  • fs代表font-size
  • lh代表line-height
  • t , b , l , f , tb , lr 代表方向
  • 数值 均为 px 单位
  • 注意 如果 没有 方向(p-xs-20)则代表四个方向(padding: 20px)
  • 注意 lh 特殊,值的语义不为 px 代表的是 1.0 - 2.0 = 10 - 20;
  • lh-sm-18(line-height: 1.8) lh-xs-15(line-height: 1.5);

工具类

浮动相关

// 左浮动
.float-left {
  float: left;
}

// 右浮动
.float-right {
  float: right;
}

// 清除浮动影响
// 防止margin溢出
.clearfix {
  @include clearfix;
}

宽度和高度最大化

// 宽度撑满父容器
.width-full{
  width: 100%;
}

// 高度撑满父容器
.height-full{
  height: 100%;
}

文字属性相关

// 居左
.text-left{
  text-align: left;
}

// 居中
.text-center{
  text-align: center;
}

// 居右
.text-right{
  text-align: right;
}

// 加粗
.text-bold{
  font-weight:bold;
}

// 一行显示溢出隐藏
.text-nowrap{
  white-space: nowrap;
  text-overflow: ellipsis;
  overflow: hidden;
}

// 大写
.text-uppercase{
  text-transform: uppercase;
}

响应式图片

.img-responsive{
  display: block;
  max-width: 100%;
  margin-left:auto;
  margin-right:auto;
}

横向列表

// 横向列表 float 实现方式
ul.list-float,
ol.list-float {
  @extend .clearfix;
  li {float: left}
}

// 横向列表 inline-block 实现方式
ul.list-inline-block,
ol.list-inline-block {
  li {display: inline-block}
}

// 横向列表 flex 实现方式(如果开启了弹性布局)
ul.list-flex,
ol.list-flex {
  display: flex;
}

响应式背景

.bg-cover {
  background-size:cover;
  background-position:center;
}

强制隐藏元素

.hide{
  display: none !important;
}
