⚑TLDR

For a dynamic, responsive web experience, avoid using tables for layout. CSS Flexbox and Grid, in contrast, adjust smoothly to varied screen sizes, enhancing user accessibility and experience.

<div style="display: flex; justify-content: space-between;"> <!-- Your side menu here. No? How about a joke? πŸ”₯ --> <div style="flex-grow: 1;">Menu</div> <!-- Here's where all the fun happens. Just like coding, right? --> <div style="flex-grow: 2;">Main Content</div> <!-- Ad goes here. Unless you enjoy a cleaner internet! 🌍 --> <div style="flex-grow: 1;">Ads</div> </div>

The snippet above creates a responsive layout optimized for all screens.

Evolution: Tables to modern layout methods

Using tables for layout, while a common historical practice, is an outdated technique. Tables create inglexible and static layouts, complicating changes and responsiveness.

The path to better maintainability

Adopting semantic HTML and CSS over table layouts improves maintainability. Modifications to designs or layouts are implemented more efficiently, sparing the tedium of HTML rewrites and saving time.

Modern layout management

The advent of Flexbox and Grid in CSS changes the game. They offer better layout controls, impeccable alignment and spacing options, which are difficult and clumsy to achieve with tables.

Accessibility and parsing: A hidden trap

Tables for layout complicate the life of assistive technologies like screen readers. They understand tables as a structure for data, and misuse can throw them off the scent.

Performance considerations

Tables come with a complex layout algorithm. This complexity, unintended for layout control, can slow down rendering speed. Misuse of tables can hamper automated parsing and impact search engine indexation, undermining the visibility of your site.

Future-proofing and adaptability

CSS-based layouts are adaptable and versatile. In contrast, tables tie your presentation to your HTML, rendering it resistant to future browser updates, design trends, and user expectations.
