Scrollify is a jQuery plugin that moves a page between selected vertical sections. Load jQuery and Scrollify, then initialize it with a CSS selector shared by the panels you want to snap between. The pattern below covers setup, named sections, ordinary scrolling inside content, and the checks to make before shipping.
How to make a website scroll one section at a time
Scrollify works with elements selected by CSS; they do not have to be HTML <section> elements. Its project describes it as “A jQuery plugin that assists scrolling and snaps to sections.” The example assumes jQuery and the Scrollify script have already loaded, in that order.
- Add the dependencies. The project documentation requires jQuery 1.7 or newer and documents installation through Bower or npm. Confirm the package and dependency versions used by your build; the version records differ (see the project README and the package listing).
- Mark the panels. Give each intended panel the same selector, such as
.panel. - Initialize on DOM ready. Call
$.scrollify()with the selector in thesectionoption.
<div class="panel">First panel</div>
<div class="panel">Second panel</div>
<script>
$(function () {
$.scrollify({ section: ".panel" });
});
</script>This is the minimal initialization pattern, not a complete dependency install: include jQuery and the Scrollify script before this code. Consult the project documentation and demo for the defaults and the configuration supported by the version you install.
Configure sections, hashes, and page behavior
Scrollify documents options for section selection, naming, interstitial areas, animation, offsets, scrollbars, ordinary-scroll exceptions, section heights, overflow, touch behavior, and callbacks. Set only what your page needs; defaults and behavior depend on the configuration.

Link directly to a named panel
Set sectionName to the data-attribute name used on panels, and enable updateHash if the URL should reflect the current panel. For example, with the default attribute name, a panel can use data-section-name="about". The URL hash can then identify that section. Check fragment links and browser history in your own page, and avoid element IDs that conflict with the fragment names Scrollify generates.
Keep headers, footers, and embedded content usable
Use interstitialSection for areas such as a header or footer that should not behave like full-height panels. Set standardScrollElements for regions that should retain ordinary scrolling, such as a map or embedded frame. For panel content taller than the viewport, overflowScroll allows scrolling within the overflowing section. Verify the result with actual content: collapsed or improperly contained elements can lead to incorrect section-height calculations.

Tune movement and respond to layout changes
Options include easing, scrollSpeed, offset, scrollbars, and setHeights. Scrollify also documents lifecycle callbacks named before, after, afterResize, and afterRender. Use them only where your application needs to coordinate work with section transitions or rendering.
The API documents animated and instant movement by index or named hash, next/previous navigation, enable/disable controls, and accessors for the current panel and index. It also offers update() to recalculate positions and dimensions, and destroy() to remove event handlers and assigned heights. These are useful for navigation controls and dynamic layouts, but test them against your installed version and markup.

Decide whether section snapping fits the page
Scrollify is intended for vertical section movement; its FAQ says horizontal scrolling is not supported. Consider the content and interaction needs before applying snapping across a whole site.
- Full-page snap or continuous scroll: snapping creates deliberate panel-by-panel movement; conventional scrolling may better suit long-form reading.
- Fixed-height panels or overflowing content: short, viewport-sized panels are simpler. Long panels need carefully tested internal scrolling and height calculations.
- Hash navigation or clean URLs: hashes can support deep links, but verify direct loads, back/forward history, and fragment collisions.
- Touch enabled or disabled: the project documents touch handling and a disable method. Its statement that the plugin works well on mobile is a project claim, not independent testing; check it on the devices and browsers your audience uses.
Accessibility and interaction checks before launch
The documentation does not establish that Scrollify automatically handles accessibility concerns. Test the experience rather than assuming section snapping is accessible by default.

Compatibility and maintenance: what the records establish
The project README states a jQuery 1.7+ requirement and claims support for IE 8+, Chrome, Firefox, Opera, and Safari. The demo repeats the jQuery requirement. These are project-published statements, not a guarantee for current browser releases.
Version records should not be conflated: the jQuery Plugin Registry lists version 0.1.3 dated June 29, 2014, with a jQuery >=1.6 dependency, while metadata for jquery-scrollify version 1.0.12 reports a jQuery >=1.7 dependency. Check the exact package version and compatibility in your environment. A historical GitHub issue reports trouble calling update() after resize when setHeights is false; it is one old report, not proof of a current defect. Reproduce that case if your implementation uses those settings.

Troubleshooting common problems
- Nothing snaps: Check that jQuery and Scrollify load before initialization, that initialization runs after the DOM is ready, and that the configured
sectionselector matches the intended elements. - The console reports
$.scrollifyis undefined: Confirm the plugin script loaded successfully and after jQuery; check the script URL, bundler configuration, and load order. - Panel heights or positions are wrong: Check the section selector, content visibility and containment, and overflow settings. After content or layout changes, try the documented
update()method and test resizing with the exactsetHeightsconfiguration in use. - Long content cannot scroll normally: Configure
overflowScrollwhere needed and exempt controls or embedded regions withstandardScrollElements. Test the actual nested content rather than an empty panel. - Header or footer snaps as a panel: Configure the relevant non-panel area with
interstitialSection. - A section link lands incorrectly: Check the
sectionNamedata attribute,updateHashsetting, direct fragment load, and possible collisions between generated fragments and element IDs. - Movement feels unsuitable on touch or with motion preferences: Test on target devices and provide a way to disable or adapt snapping where needed; the project documents disable controls.
