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 🙏

Readme

postcss-px-to-vw

A plugin for PostCSS that converts pixel units to vw unit.

postcss-pxconverter

目前存在的问题

  1. rem 布局受到 root font-size 影响,如果 Android 开启了字号放大模式,会导致整个布局崩盘。
  2. Android 下 viewport scale 强制为 1,一些 Canvas 绘制的内容略为模糊。部分 Android 设备改变 scale 有 bug,机型太多较难定位。

改进的思路

保留原本 rem 方案的基础上,对于非 font-size 的单位渐进增强,在 rem 的规则下面新增一条 vw 的规则进行覆盖。此方案可以保证低版本 Android 的兼容问题。

 注意

如果原来是rem,也会新增一条 vw 的规则进行覆盖。 例如 padding:1rem; 会被转换成 padding:1rem;padding:1vw;

可能的缺陷

  1. CSS 体积增加。
.title {
  /* you can override pixel replacement by adding a "px" *
   * comment after the declaration if you want to keep.  */

  font-size: 32px; /*px*/
  padding: 16px 0 18px;
}
.title {
   /* you can override pixel replacement by adding a "px" *
   * comment after the declaration if you want to keep.  */

  font-size: 32px; /*px*/
  padding: 4.444444444444445vw 0 5vw;
}

Usage

Plug it into your PostCSS configuration.

var option = {
  vwUnit: 375, minPixelValue:2
};


postcss([require('postcss-pxtoremvw')(option)])
