21
22 1. The CSS3 stylesheet production, such as `p { color: purple }`.
23 2. The CSS3 rule production, such as `a[href=~"https:"].foo#bar`.
24 3. CSS3 declaration productions, such as `color: red; margin: 2px`.
25 4. The CSS3 value production, such as `rgba(0, 0, 255, 127)`.

28
29 * <span class="good">`<p style="{{ .Params.style | safeCSS }}">…</p>` → `<p style="color: red;">…</p>`</span>
30 * <span class="bad">`<p style="{{ .Params.style }}">…</p>` → `<p style="ZgotmplZ">…</p>`</span>
