What this is

This release added live preview to the confirming step. When you type a target value, Lens applies it to the clicked element on the page in real time, so you see the change before you commit to a diagnosis. No save. No reload. The element just updates while you type.

It also added a dynamic warning. If the value you typed will be overridden by a higher-specificity rule, Lens says so and names the real source doing the overriding: a theme, a plugin, a page builder, an inline style, or a script. Pseudo-elements got the same treatment, so ::before and ::after now have selectable property cards, live preview, and full triage parity. The property list collapses while you type so the popup stops sitting on top of the element you’re trying to watch.

What it answers

– how do i preview a css change before applying it on my site
– why does my css change not hold even though it looks right
– what is overriding my css when my change keeps getting ignored
– how to see live css changes without editing the stylesheet
– how do i style a before or after pseudo element that won’t change

Why we built it

The diagnosis is more useful when you can watch the change land before you trust it. A value that won’t survive the cascade should say so while you’re still typing it, not after you’ve pasted it.
