Thanks that helps too. I was actually referring to make the glow effect space bigger, that is wider and taller. Please.
Topic summary
Goal: strengthen and enlarge a glow effect on Dawn 15 for banner titles/buttons using CSS.
Original setup: a ::after pseudo-element under .banner__heading uses box-shadow on hover for a white glow. The effect was too subtle, and the requester wanted the glow area to be wider and taller.
Proposed approach 1: use text-shadow on .banner__heading:hover with multiple layered shadows to intensify the glow. Implementation steps provided (edit base.css/theme.css/custom.css) and a result screenshot, but the requester preferred box-shadow instead of text-shadow.
Final approach (box-shadow focused): keep the ::after pseudo-element and increase its size (e.g., width: 96%, height: 10px). Intensify the glow by repeating the same box-shadow multiple times and increasing the blur radius (e.g., 60px) and background color opacity on hover. Key tunables: width (length of underline), height (thickness), blur radius (glow spread), and number of repeated shadows (strength).
Notes: code snippets and screenshots are central to understanding the change. Status: likely addressed with the final code; awaiting confirmation from the requester.
