<een sections. In a single-page self-contained HTML." No JS dependencies. All you need to do is Design! Content can be updated easily by designing one or more special frames, visible on this page at all times, an d use the automatic preview frame to generate the custom page. Design changes can also be previewed. Additional links can be added to the page without designing a separate frame. This link to Monomco will open in a new window, as it is not an item header. More control over the look and the structure of the page can be achieved by editing the HTML with e.g. VSCod e and choosing the iframe source . Header place-holder First visible section (or an indicator that something is loading) This frame is the very first section or what is first visible until content loads. Otherwise the page would be completely empty. Note that this first section does not have navigation arrows, as it is the first visible section. Not shown here is also the Easter-egg: a portal that teleports the earth up and doubles it size. Import and import this library to use: useFramePreview(c) Hide scroll-bars The options allow you to specify the width to use in hiding the scroll-bar. Disabling animated headling may make the page load faster for devices with very limited capabilities (hopefully invisibly for people that ar e visually impaired). joaquintournier@Joaquins-MacBook-Pro Rival %
