I'm trying to add a hover effect to the buttons in my navigation menu, where they scale up a bit when the user hovers over them. The issue is, both the border and the background image on these buttons seem to lose quality during the transform. I initially thought the background image was the problem, even though it has a high DPI. However, since the border I designed with CSS also shows quality loss, it makes me think there's something else going on.
Additionally, I noticed a tiny seam appears between the background image and the border when the button scales. I've done a quick search online but didn't find any solutions. I really need to get this fixed quickly, so any help would be greatly appreciated! Here's the code I'm using for the transformation:
#nav > a {
transition: transform 0.3s ease-in-out;
}
#nav > a:hover {
transform: scale(1.01);
}
Let me know if you need more details. Thanks!

For the issues with quality loss, it can sometimes help to switch from images to vectors for your button backgrounds. This ensures that scaling stays smooth and doesn’t lose clarity. Also, since you're experiencing blurriness on the CSS border, you might want to double-check the border properties or consider adjusting the scale factor slightly.
I hear you! Those quality loss issues can be pesky. You could also try adjusting the hover scale a bit lower (like scaling to 1.01 instead of 1.05) to see if that improves the visuals. It might reduce the seams you're seeing.
You might want to try using the `will-change` property on your buttons. It can help improve the rendering performance when transforming elements. Also, apply `transform: translateZ(0);` as a technique to push the rendering work onto the GPU, which can enhance the visual quality during transformations. Keep in mind to use it sparingly, as it can be resource-intensive if overused.
