When enabled, the entire site will reflow content from right-to-left. Every element in the theme has been restyled to ensure it looks great in this mode which aids authors who wish to generate content in RTL languages.</p><p>RTL is controlled on a per-language basis so you can mix and match both RTL and LTR content in your projects and the theme will respond accordingly.</p><h2 id=automatic-image-resizing class="relative group">Automatic image resizing <span class="absolute top-0 w-6 transition-opacity opacity-0 -start-6 not-prose group-hover:opacity-100"><a class="group-hover:text-primary-300 dark:group-hover:text-neutral-700" style=text-decoration-line:none!important href=#automatic-image-resizing aria-label=Anchor>#</a></span></h2><p>A big change in Congo 2.0 is the addition of automatic image resizing. Using the power of Hugo Pipes, images in Markdown content are now automatically scaled to different output sizes.
