Web Design Standards Perforamance Guide

To implement this guide a team was assembled to do user research with different government agencies to see where website performance was falling short. The team also researched different open source tools for performance tracking and started to make some decisions on how to best guide people. More details on the research can be found on the research report.

The research showed that most teams were not consistently tracking performance as a project evolved and would benefit from doing so. Performance tracking became the focus of the guide, with a bulk section on how to implement performance tracking on almost any team. Additonally, there's guidance on HTTP/2 and a glossary of performance concepts.

Code For America Summit Accessibility Panel

Code for America is a non-profit working to improve government technology through it's year-long fellowship program and volunteer city brigade programs. I was part of a panel discussion with three other experts talking about web accessibility particularly related to the US Web Design Standards.

For the panel, we discussed how to effectively ensure a government style system, such as the Web Design Standards, can remain accessible for all that use it. A main point of the discussion was how to design and develop with accessibility in mind from the start of the project, continually keeping it at the forefront as new parts are added. This contrasts with a more typical approach of fixing accessibility issues at the end of a project before launch. I've found the tactic of keeping accessibility in mind from the start and throughout a project is the most effective method of ensuring the project is always accessible.


The specific pages for the talks at the summit have been taken offline, but general information about the summit can be found on the CFA Summit website.

How we share style across multiple sites 18F blog post


The cloud.gov, a PaaS for government, front end has multiple different site's that all need a universal style and consistency. In order to keep the styling code for these different sites without having repition, a style library was needed that could be brought into each of the different sites. This led to the creation of cg-style or cloudgov-style, an npm deployable style library.


Having found that many other 18F and government projects also required sharing styles between multiple sites or repositories, I wrote a blog post to articulate the benefits and difficulties of maintaining a shared style library. It discusses the CSS architecture, how we used SVG to create adaptable icons, how we distributed the library to make it easy to include and update, and the continuous integration and release process for the library.

18F CSS Coding Styleguide

A technical document to provide 18F and government developers with guidance on best practices for writing CSS.


In order to address the problem of hard to maintain CSS at 18F , I did user research interviews with developers on the 18F team to find what the largest problems were in CSS codebases. I found that code style was inconsistent, there were bad practices around having too high of specificity and organization and naming conventions were not well defined.


After having looked for comprehensive style guides that reflected 18F's values and character and not finding anything that matched well, it was decided I would write an 18F CSS Styleguide to be used internally and shared around the government. This guide includes general CSS formatting guidance, how to architect CSS, naming schemes and much more on how to write great CSS. The CSS guide was eventually folded in with a larger front end guide for 18F.
