Glide adds four blocks that work together to build scroll-driven sections and\nsliders, with no shortcodes and no page-builder lock-in. Everything renders\nserver-side, so a step or a slide is real content in your post, and a Sticky\nChapters section is readable with JavaScript switched off.<\/p>\n\n
Sticky Chapters<\/strong> \u2014 a contents rail that stays in view beside your steps and\nhighlights the one being read, built from the headings you already wrote. Put it\non either side or across the top, with numbered, dot or plain markers, a\nprogress line and a step counter. On phones it becomes a strip above the steps\nthat scrolls sideways to keep the current chapter in view. A step can take a\ntitle of its own, or stay on the page but out of the rail.<\/p>\n\n Content Slider<\/strong> \u2014 one to six slides per view, with arrows, dots, a progress\nbar or no controls, autoplay, loop, drag-free scrolling, keyboard navigation and\nthumbnails below, above or beside the slides. Fit it to the tallest slide, or\nset a height for desktop, tablet and phone. An overlay block holds content of\nits own on top of the slider.<\/p>\n\n Video backgrounds<\/strong> \u2014 from your Media Library, YouTube, Vimeo or another\noEmbed provider, with play and mute buttons for Media Library, YouTube and Vimeo\nvideo. In the slider, a video pauses when its slide leaves. A Media Library\nvideo with no thumbnail gets a poster made from one of its frames (see \"Video\nthumbnails use ffmpeg\" below).<\/p>\n\n While you edit<\/strong> \u2014 the sidebar warns you about settings that cost readers\ncontrol: arrows, dots and thumbnails all switched off, controls hidden until\nhover, or a video background with no play and mute buttons.<\/p>\n\n Glide Pro adds three more sticky-scroll layouts (Sticky Media, Stacking Cards\nand Horizontal Pin), a marquee that loops any blocks left, right, up or down,\nthe Scale and Barn Doors transitions for the content slider, and chapter links\nmade from each step's title. It is a separate plugin, sold at\nhttps:\/\/theghostlab.io\/glide<\/a>, and this plugin contains none of its features.<\/p>\n\n Glide sends nothing about your site, your visitors or your content anywhere. It\nhas no telemetry and no update server \u2014 updates come from WordPress.org like any\nother plugin in the directory. Settings \u2192 Glide links to the GhostLabs website\nand to your GhostLabs account; those are links you choose to follow, and the\nplugin itself sends nothing to either. This section covers the two server-side\ndetails a reader of the source will find and should not have to guess about,\nand the video providers a slide can embed.<\/p>\n\n When you give a slide a video from your Media Library and that video has no\nposter image, Glide extracts a single frame so the slide has something to show\nbefore the video loads. It runs Nothing about this is required. A slide with a poster image set, or a video from\nYouTube or Vimeo, never reaches it at all.<\/p>\n\n A slide with a YouTube or Vimeo video background embeds that provider's player,\nwhich loads from the provider and is subject to their terms and privacy policy \u2014\nthe same as any embedded video anywhere on your site. It happens only on a slide\nwhere you have set one, and only in the visitor's browser.<\/p>\n\n While you are editing, pasting a video URL fetches a thumbnail for the slide\npreview: from That thumbnail is saved as the slide's poster image at the provider's address.\nThe poster appears only in the thumbnail strip, so on a slider with thumbnail\nnavigation each visitor's browser loads it from Any other video URL is embedded through WordPress's own oEmbed support: your\nserver asks that provider for its embed code, keeps the answer for a day, and\nthe visitor's browser loads the provider's player. Which provider, and whose\nterms apply, depends on the URL you paste. If the provider has no embed for\nthat URL, the slide shows no video, and your server asks again an hour later.<\/p>\n\n Glide's compiled JavaScript and CSS are minified.
