When capturing a Pinterest board using Puppeteer, a persistent sticky header interferes with the screenshot. How can I remove it? See the revised code snippet below:

const browserTool = require('puppeteer');

(async () => {
  const browserInstance = await browserTool.launch({ headless: true });
  const pageView = await browserInstance.newPage();
  await pageView.goto('https://pinterest.com/exampleBoard');

  // Locate and remove the sticky header using a CSS selector
  const headerElem = await pageView.$('header.sticky');
  if (headerElem) {
    await pageView.evaluate(el => el.remove(), headerElem);
  }

  // Simulate scrolling with a limited number of scrolls
  await pageView.evaluate(async () => {
    let scrollCount = 0, maxScrolls = 10;
    while (scrollCount < maxScrolls) {
      window.scrollBy(0, window.innerHeight);
      scrollCount++;
      await new Promise(res => setTimeout(res, 500));
    }
  });

  // Capture full-page screenshot
  await pageView.screenshot({ path: 'new_screenshot.png', fullPage: true });
  await browserInstance.close();
  console.log('Screenshot saved as new_screenshot.png');
})();

I encountered a similar challenge when capturing full-page screenshots with Puppeteer. In my experience, removing the element outright sometimes doesn’t completely solve the display issue, especially if the site re-renders elements dynamically. One approach that worked for me was to inject some custom CSS after removing the element. This prevented any persistent reappearance by overriding related styles on the page. I used page.evaluate to insert a style element that targeted the sticky header class. This ensured that any delayed rendering didn’t bring back the header. This method proved reliable for my use cases and might be worth trying here.
