How I Built a Visual CSS Grid Debugger in React

Ever struggled with debugging why your CSS grid isn't behaving as expected? I recently built a small React component that visualizes grid lines and gaps in real-time using a canvas overlay. It's been a lifesaver for understanding complex layouts. Here's the core logic:

javascript
function GridOverlay({ columns, rows, gap }) {
const canvasRef = useRef(null);

useEffect(() => {
const canvas = canvasRef.current;
const ctx = canvas.getContext('2d');
const width = canvas.width;
const height = canvas.height;

ctx.clearRect(0, 0, width, height);
ctx.strokeStyle = 'rgba(0, 150, 255, 0.3)';
ctx.lineWidth = 1;

// Draw vertical lines
const colWidth = (width - gap * (columns - 1)) / columns;
for (let i = 0; i <= columns; i++) {
  const x = i * (colWidth + gap);
  ctx.beginPath();
  ctx.moveTo(x, 0);
  ctx.lineTo(x, height);
  ctx.stroke();
}

// Draw horizontal lines
const rowHeight = (height - gap * (rows - 1)) / rows;
for (let i = 0; i <= rows; i++) {
  const y = i * (rowHeight + gap);
  ctx.beginPath();
  ctx.moveTo(0, y);
  ctx.lineTo(width, y);
  ctx.stroke();
}

}, [columns, rows, gap]);

return ;
}

For more complex debugging, I've been using a tool called CSSGridInspector that overlays this on any page. What's your favorite way to debug CSS grid layouts?

I've been experimenting with geo-specific SEO analysis lately, and one of the biggest challenges has been getting accurate local search results without constantly switching VPNs or changing locations manually.

Recently, I started testing SERPSpur's Local Search Spoofing Tool, which lets you view search results by country, city, region, and language. It made it much easier to compare rankings across different locations and spot gaps in local SEO campaigns.

Here's a quick example:

curl "https://serpspur.com/tool/local-search-spoofing-tool/?keyword=hotel&country=FR&city=Paris&language=fr"

This returns search results as if the query was made from Paris, France. I've been using it to compare rankings across multiple European cities and identify where localized content needs improvement.

A few use cases where it's been helpful:

Local SEO audits
Multi-location rank tracking
International SEO testing
Competitor research by region

How are you handling location-based SERP testing? Are you using VPNs, proxies, or dedicated SEO tools?
