First things first, create a new page for your loader or just add the loader element to an existing page. This is where you'll design your custom loader animation.

1. Head over to the Webflow Designer.
2. Drag and drop a Div Block from the Add Elements panel.
3. Give this div block a class name, something like loader.

1. Select the loader div block.
2. In the Style panel, set the width and height (e.g., 100px by 100px).
3. You can add a background color or an image if you want a custom graphic.
4. Center the loader by setting its position to Fixed and aligning it to the center.

1. Go to the Interaction panel.
2. Add a Page Load interaction.
3. Choose Start Animation for when the page starts loading.
4. Click + to create a new animation and give it a name, like Loader Animation.

1. Inside your new animation, click on the + button to add a new keyframe.
2. Choose the loader element.
3. Add different transformations, opacity changes, or other effects by clicking on the transformations and defining the properties.
4. For example, to create a spinning loader:

• Set the initial rotation to 0 degrees.
• Add another keyframe at the end of the animation duration (e.g., 2 seconds) and set the rotation to 360 degrees.
• Make sure to set the easing to Linear to ensure smooth continuous rotation.

Set the animation to loop continuously:

1. In the Interaction panel, find the loop options and enable loop for the created animation.

1. Initially hide the main content of your page by selecting all elements except the loader and setting their initial display to none.
2. Add another interaction step in your Page Load animation to show the content after a delay (e.g., when the page has finished loading).

1. Go back to the Interactions panel.
2. Set an interaction for Page load (When page finishes loading).
3. Add a new animation (e.g., Hide Loader).
4. In the new animation, set the loader element’s opacity to 0% and then hide it (display: none).
5. Set the display style of the main content back to block or as needed.

1. Preview the page to see if the loader animation works as intended.
2. Make adjustments as needed in the timing and effects to perfect the loader animation.

Once you're happy with the custom loader animation, publish your website to see the loader in action on the live site. Ensure all interactions are working smoothly, and the loader seamlessly transitions to the main content.
