Show HN: Pure CSS silky Border line animation(open-source code) Use only CSS to achieve a silky border line animation effect. Key implementation ideas include: 1. Perspective effect: Create a border effect by setting up two nested elements with the parent element having 1 pixel padding. 2. animation: Create an absolutely positioned child element and use the animation property to move it uniformly along the border of the parent element. 3. Uniform animation: By calculating the path and distance of the element movement, adjust the percentage of key frames to ensure uniform animation. 4. Rounded corners: Add rounded corners to the parent and child elements, and adjust the position of the animation elements to fit the rounded corners. 5. Animation optimization: Adjust the animation trajectory at the rounded corners to ensure a natural and smooth transition. 6. Blur shadow: Achieve the shadow effect by setting the background radial gradient of the child element and using the backdrop-filter attribute to add a blur effect. https://ift.tt/1Wl7ExJ https://ift.tt/1Wl7ExJ September 29, 2024 at 04:29PM
