`css/reset.css` sets multiple font style attributes, including `font-family`, of many elements (including `code` and `tt`) to `inherit`, which causes them to inherit the value of that style attribute on their containing elements. `css/typography.css` then undoes the damage for some elements (e.g. `em`, `strong`) by setting their font attributes appropriately, but does not fix the `code` and `tt` elements. Placing the following CSS rule in css/typography.css would make `code` and `tt` elements useful again: ``` code, tt { font-family: Inconsolata, "Lucida Console", "Droid Sans Mono", Cousine, Courier, monospace; } ```
