/*
 * I-Square Article Styles
 * File: isq-article.css
 *
 * Usage:
 *   1. Load this stylesheet on pages that display published article content.
 *   2. Load the same stylesheet inside TinyMCE using the content_css option.
 *   3. Wrap each article in <div class="isq-article"> ... </div>
 *
 * All selectors are scoped to .isq-article so these rules do not intentionally
 * style unrelated parts of the host I-Square website.
