Click the “Add Twenty20” button in your editor 2. Select your before and after images 3. Customize settings as needed 4. Insert and publish ## FAQ ### How it works? Twenty20 works by stacking two images on top of each other. As the slider moves across the image. ### Quick Example [twenty20 img1=”” img2=”” direction=”vertical” offset=”0.5″ align=”right” width=” 60%” before=”Before” after=”After” hover=”true”] ### Shortcode Parameters * `img1` – image ID. * `img2` – image ID. * `offset` – range from 0.1 to 1.0. * `direction` – `horizontal|vertical`. * `align` – `none|right|left`. * `width` – supports both px and %. * `before` – text for the “before” label. * `after` – text for the “after” label. * `hover` – `true` or `false`. ### How to add before-after slider? Check the demo [Video](https://www.youtube.com/watch?v=1cQ9rhL-t70) demo. ### How do I add a slider with the block editor? Add the “Twenty20 Before-After” block, pick the before and after images, then tune the starting position, direction, labels, alignment, width, and mouse-hover behavior in the block sidebar. The canvas shows a live preview that updates as you change settings — click the preview to jump back to the block settings, or use the Preview/ Edit toggle in the block toolbar. The block uses the same secure renderer as the shortcode. ### How do I add a widget? Watch the [video demo](https://www.youtube.com/watch?v=1cQ9rhL-t70) on YouTube. ### Can I use more than one slider in a single post or page? Yes, the Twenty20 plugin allows users to add unlimited before-after sliders. ## Reviews ![](https://secure.gravatar.com/avatar/f3d659e966383b6cb4a6f0bdd74ee3baaa1092be9e2a0a7c4c75781fe01ac210? s=60&d=retro&r=g) ### 󠀁[Great plugin, fast support](https://wordpress.org/support/topic/great-plugin-fast-support-54/)󠁿 [bing4](https://profiles.wordpress.org/bing4/) Agosto 12, 2024 Great plugin, fast support, simple, easy to use. ![](https://secure.gravatar.com/avatar/9ce6ff06228d96fe00b9c08997c548b95c07ec684b8683d1f965ed6717569f35? s=60&d=retro&r=g) ### 󠀁[No Longer Working](https://wordpress.org/support/topic/no-longer-working-159/)󠁿 [](https://profiles.wordpress.org/vegasdood/) Setyembre 24, 2023 Type for an update or get pulled. ![](https://secure.gravatar.com/avatar/35cbcb591e6ef4013bbd838ea1cb93cbfb26afd446df2946f7a1824692aa88c5? s=60&d=retro&r=g) ### 󠀁[ブロックエディター未対応](https://wordpress.org/support/topic/%e3%83%96%e3%83%ad%e3%83%83%e3%82%af%e3%82%a8%e3%83%87%e3%82%a3%e3%82%bf%e3%83%bc%e6%9c%aa%e5%af%be%e5%bf%9c/)󠁿 [tsutlnps149](https://profiles.wordpress.org/tsutlnps149/) Marso 24, 2023 恐らく、このプラグインはブロックエディターに対応していないので、Gutenbergでは画像 が挿入できないです。 あと、lazyload.jsや"loading=lazy"を使用すると、表示されなく なったり画像下に空白ができてしまったりするバグがあるため、画像表示が崩れます。 ![](https://secure.gravatar.com/avatar/69b138e5efa7d3db2c346235fc5a3bb933b9443a3e44ba74a01975c09b508920? s=60&d=retro&r=g) ### 󠀁[Suberb plugin!](https://wordpress.org/support/topic/suberb-plugin/)󠁿 [boraboraphotovideo](https://profiles.wordpress.org/boraboraphotovideo/) Marso 21, 2022 Wonderful functionality for a photographer or photo re-toucher / editor.
