I have refactored this site thoroughly. Content is similar, but very little remains of the old structure. Improvements include:

• SASS/SCSS, using NPM processing on the dev server
• Block-Element-Modifier (BEM) naming convention
• A more flexible grid system, still without using a framework
• Relative units for all site structure
• Improved responsive images in HTML and CSS
• More (and more engaging) microinteractions and transitions
• Pure CSS modal windows, using JavaScript only for accessible keyboard navigation

As always, accessibility is a prime consideration with all enhancements.
