Here is the prompt, code and working deployment of K-Scrubber that helps you removing unwanted characters from text.
The “K-Scrubber” Project Prompt
Objective: Create a high-end, single-page web utility called “K-Scrubber.” The tool allows users to paste text, specify characters to remove, and receive a “cleaned” version where those characters are replaced by a single space, ensuring no double-spaces remain.
1. Design & UI Requirements
Visual Style: Modern “Glassmorphism” or “Apple-esque” minimalism. Use a soft background gradient (e.g., #e0eafc to #cfdef3).
The Card: A centered, semi-transparent white glass container with a subtle backdrop-filter: blur(10px) and a soft 0 20px 50px rgba(0,0,0,0.1) shadow.
Typography: Use “Inter” or “Poppins” (system-font fallback). Headings should be bold and dark (#2d3436), body text should be clear.
Interactions: * Buttons should have a subtle scale effect (transform: scale(0.98)) when clicked.
Use a primary accent color like Indigo (#6366f1) for the action button.
Include a “Copy to Clipboard” button that shows a “Copied!” tooltip or toast notification.
2. Functional Logic (The “Brain”)
The JavaScript must follow these specific steps in order:
Capture Inputs: Take the string from inputText and the string from targetChars.
Escape Special Characters: Automatically escape any special regex characters (like ., *, ?) entered in the targetChars field to prevent script errors.
The Replacement Logic:
Step A: Use a global Regular Expression to find all instances of targetChars and replace them with a standard space ( ).
Step B: Use the regex /\s+/g to find any sequence of multiple whitespace characters (spaces, tabs, newlines) and replace them with a single space.
Step C: Apply .trim() to ensure the final string doesn’t start or end with an unnecessary space.
Real-time Option: (Optional but preferred) Add a toggle to “Clean as I type.”
3. Layout Structure
Header:Small “K” logo and the title “K-Scrubber.”
Main Input: A large, auto-expanding textarea.
Control Row:A text input for “Characters to Scrub” and a “Clean Text” button.
Output Area:A read-only textarea with a different background color (e.g., very light indigo) to distinguish it.
Footer: A “Characters Removed” counter to show the user how much “junk” was scrubbed.
4. Technical Constraints
Single File:Provide everything in one index.html file (HTML5, CSS3, Vanilla JS).
Responsive: Must look perfect on mobile devices and ultrawide monitors alike.
Clean Code:Use semantic HTML and well-commented JavaScript.
