Smart Comment Box with Toolbar

A plain gets the job done. But it doesn't make users want to comment.
I built a comment box that feels premium — the kind you see on modern platforms like Linear, Notion, and GitHub. 🎁

What I Built
Smart Comment Box with Toolbar — a premium, rich-text style textarea component featuring:
✅ Integrated bottom action bar with formatting icons (image, emoji, link)
✅ Live character counter (0 / 500)
✅ Purple focus-within border highlight
✅ Custom CSS scrollbars
✅ "Publish" button with arrow icon
✅ Uses Tailwind's focus-within for seamless container highlighting
✅ Zero JavaScript for the styling — pure Tailwind CSS
✅ Perfect for blog comment sections, messaging apps, and review forms

See It in Action

The Design Breakdown
Focus-Within Container Highlight
When the user clicks inside the textarea, the entire container gets a purple border glow — not just the input itself. This is Tailwind's focus-within utility doing the work — no JavaScript needed. It feels polished and intentional.
Bottom Toolbar
The action bar at the bottom transforms a plain textarea into a rich experience — image upload, emoji picker, and link icons sit neatly on the left, while the character counter and Publish button anchor the right side.
Live Character Counter
"0 / 500" updates as users type — setting clear expectations and encouraging users to be concise. A small UX detail that reduces frustration and improves comment quality.
Custom Scrollbars
The custom styled scrollbar matches the component's aesthetic — no ugly default OS scrollbars breaking the design.
