### Overview
Research the feasibility and impact of implementing alternative Accessibility techniques, so that Hack for LA's website can score the highest Accessibility rating possible, while still being easy to use for all visitors.

### Details
Zoom functionality in modern browsers ensures that the WCAG 1.4.4 guideline on resizing text is satisfied, but there are alternative techniques for compliance that offer accessibility advantages. In this issue we will research the feasibility and impact of implementing alternative techniques described in the guideline, in particular: (1) providing accessibility controls on the page, and (2) Specifying relative font sizes and resizing text containers and layout regions to scale with text size

### Action Items

- [ ] Research the impact of implementing:
- [G178: Providing controls on the Web page that allow users to incrementally change the size of all text on the page up to 200 percent](https://www.w3.org/WAI/WCAG21/Techniques/general/G178.html)
- [ ] Research the alternative of ensuring that text containers resize when the text resizes AND using measurements that are relative to other measurements in the content by using one or more of the following techniques:
- [C28: Specifying the size of text containers using em units](https://www.w3.org/WAI/WCAG21/Techniques/css/C28.html)
- Techniques for relative measurements
