Resolve the floating elements issue by making use of the .clearfix class on your parent div. This application of CSS pseudo-elements ensures that the parent container expands to accommodate its floated child elements:

/* Adding a bit of 'clear' sky after the storm of floats */
.clearfix::after {
  content: "";
  display: block;
  clear: both;
}

Attach .clearfix to your div to keep the floats in check:

<div class="clearfix">
  <!-- Your floating 'sailors' are kept aboard -->
</div>

To maintain the flexibility of your layout and reduce static code, avoid specifying a height for your div. Allow the content, like a gentle wind, to guide your divs dimensions.

Employing modern layout designs

Whilst the clearfix hack has held its own, contemporary CSS promotes more powerful tools like the Flexbox and CSS Grid strategies. These offer a sturdy layout and can take care of float-related anomalies:

.container {
  /* 'Flex'ing those CSS muscles */
  display: flex; /* Or 'grid' up for a different workout */
  flex-direction: row; /* Or 'column' for a vertical swing */
}

Optimizing layout for all screen sizes

Resilient design lies in its adaptability, so remember to incorporate responsive design. With media queries, your layout stays uniform across devices. Additionally, optimizing images creates faster loading times, while scalable SVGs ensure high-quality visuals.

To ensure accessibility, use semantic HTML - think of it as adding braille to your website. Practicing secure HTTPS and employing web development best practices future-proofs your project. Lastly, never underestimate the power of performance optimization - even the smallest savings in load time can vastly improve user experience.

Futuristic features: BFC and flow-root

Heard about the display: flow-root CSS declaration? This future gem will explicitly create a Block Formatting Context (BFC), rendering the clearfix method redundant. Get ahead by making your code modular and ready for easy refactor:

.container {
  /* The 'flow' of the future */
  display: flow-root; /* Your float watchdog */
}
