I am unable to paste icons in text blocks, which led me to use images, but images are scaling down with my animations.

To avoid shrinking images, you could try absolute positioning relative to their parent. Alternatively, set the images to a fixed size and let the sidebar (including padding) not shrink smaller than that.
