To create a Webflow button with a white stroke that fills left to right with color upon hover using timed actions or transition easing, you can utilize the interaction features available in Webflow. Here's a step-by-step guide on how you can achieve this effect:
1. Start by adding a button element to your Webflow project. You can drag and drop a button element from the Elements panel onto your canvas or use a pre-designed button style.
2. Style the button by selecting it and customizing its appearance in the Style panel. For this effect, you'll want to set the background color to the color you want to fill left to right upon hover and set the border color to white.
3. Next, you'll need to create a new interaction for the button. Select the button element, go to the Interactions panel, and click on "Add new interaction."
4. In the interaction settings, select the trigger for the interaction. In this case, we want the effect to happen upon hover, so choose "Hover" as the trigger type.
5. Now, set the initial state of the button. By default, the button should have the white stroke with no color fill. Configure the initial state styling in the "Initial appearance" section of the interaction panel.
6. To create the left-to-right color fill effect, you can use a combination of timed actions and transitions. In the interaction timeline, click on the "plus" icon to add a new action.
7. For the first action, select the button element and set the background color to the desired fill color. Set the transition duration to determine how long it takes for the fill effect to complete. For example, you can set it to 0.5s for a half-second transition.
8. Add another action and select the button element again. This time, change the width of the button to 100% to create the left-to-right filling effect. Set the transition duration to match the previous action's duration.
9. Lastly, add one more action to set the background color back to its original state (no fill) and revert the button's width to its initial value. Again, set the transition duration to match the previous actions.
10. Preview the site and hover over the button to see the white-stroked button fill from left to right with the desired color.
Remember to publish your site to see the effect in action on the live website. You can further customize the effect by adjusting the styling, timing, and transitions to align with your design preferences.
