What is the effect of using Bootstrap's lazy loading feature for images and iframes?

  • Decreases initial page load time by loading images and iframes only when needed
  • Increases initial page load time by loading all images and iframes upfront
  • Has no impact on the initial page load time
  • Improves overall performance by loading images asynchronously
Bootstrap's lazy loading feature defers the loading of images and iframes until they are needed, resulting in a decreased initial page load time as unnecessary assets are not loaded upfront.
