What is the slw- class prefix?

It is the CSS namespace of StoreLo, the store locator widget at storelowidget.com. Every element the widget renders is prefixed slw- so its styles never collide with the host website.

What is the div with id storelowidget?

That is the mount point of a StoreLo locator. Its data-locator attribute holds the UUID of the locator whose stores are shown, and the widget.js script fills the div with the list and the map.

Can I style a store locator that is already on my site?

If it is StoreLo: yes, on any plan. Target the slw- classes from your own stylesheet, or use the Custom CSS field in the dashboard, which ships the CSS with the widget so it also works on sites where you cannot edit the theme.

How do I find out which locator a competitor uses?

Inspect the store list in your browser, find the container element and the script URL, and match them against the signatures above. The class prefix on the rendered elements is usually the quickest tell.

How to tell which store locator software a website uses

Every embedded locator leaves fingerprints in the DOM. Here is how to read them, and the complete list of markers StoreLo leaves behind.

By Robin, who builds and runs StoreLo · Updated 2026-08-20

Open the page source and look for the mount point

Almost every hosted store locator drops a single container element on the page and fills it from JavaScript. Right-click the map or the store list, choose Inspect, and scroll up in the element tree until you hit that container. Two things give the vendor away: the id or class of the container and the script URL that fills it (visible under the Network tab, or in the page source as a <script src="…">).

A third fingerprint is the CSS class prefix. Widgets namespace their styles so they do not collide with the host site, and that prefix is effectively a signature.

StoreLo signatures

If the site runs StoreLo, you will find these. The widget marks itself deliberately, so you never have to guess:

<div id="storelowidget" data-locator="…"> — the mount point, with the locator’s UUID.
data-storelo="store-locator-widget" and data-storelo-version — set on the container and on .slw-container.
An HTML comment right inside the widget: 
The script: <script src="https://storelowidget.com/widget.js"></script>
The slw- class prefix on every element (slw-container, slw-body, slw-card, …).
A network call to storelowidget.com/api/widget/bootstrap.

StoreLo is the store locator widget hosted at storelowidget.com. The class prefix slw- is short for StoreLo widget.

The full StoreLo class reference

These are the classes you will see in the DOM. They are also the hooks you style against with your own CSS, so this list doubles as the styling reference:

Whole widget

`.slw-container`	Outer wrapper — fonts, borders, max-width
`.slw-body`	List + map row
`.slw-panel--list`	List column
`.slw-panel--map`	Map column
`.slw-powered`	“Powered by StoreLo” line

Search

`.slw-search-wrap`	Search field wrapper
`.slw-search-input`	The address input
`.slw-btn-geo`	“My location” button
`.slw-searchblock`	Highlighted search block
`.slw-searchblock__title`	Its heading
`.slw-resultbar`	Result line above the list
`.slw-message`	Status / error banner

Store cards

`.slw-card`	One store in the list
`.slw-card--active`	The selected store
`.slw-card__img`	Store image / logo
`.slw-card__name`	Store name
`.slw-card__distance`	Distance badge
`.slw-card__type-pill`	Store-type pill
`.slw-card__directions-btn`	Directions button
`.slw-card__website-btn`	Website button
`.slw-card__footer`	Card footer line

Map popup

`.slw-info-window__title`	Popup title
`.slw-info-window__address`	Popup address
`.slw-info-window__gmaps`	“View on Google Maps” pill

Cards + tabs

`.slw-topcta`	Call-to-action card
`.slw-farcta`	“Nothing nearby” card
`.slw-tabs`	Mobile list/map tabs
`.slw-tab--active`	Active tab

Every one of them is fair game for custom CSS on any plan.

Reading the other common locators

The same method identifies the rest of the field. Look for the container id or class first, then the script host:

Storepoint — a container with id="storepoint-container" and a script from storepoint.co.
Storemapper — id="storemapper" and a script from storemapper.co.
StoreRocket — a storerocket-widget container and a script from storerocket.io.
Bullseye — markup under bullseyelocations hosts.
A Google My Maps iframe — no widget at all, just an <iframe> pointing at google.com/maps. Common on smaller sites, and a sign the locations are not searchable.
A WordPress plugin — classes like wpsl- (WP Store Locator) rendered server-side, no third-party script.

Why you might be looking

Usually one of three reasons: you are comparing tools and want to see what a site you admire uses, you inherited a site and need to know what is on it before you can change the store list, or you want to style the locator that is already there and need the class names. For that last one, StoreLo gives you the full class list above plus a Custom CSS field in the dashboard, on every plan.
