A Look Back at Weird CSS Hacks
The evolution of the modern web was shaped by a period of extreme browser inconsistency, particularly with Internet Explorer, which forced developers to use non-standard CSS hacks to ensure functional layouts. These hacks exploited browser-specific parsing bugs and proprietary features to target specific engines. While these methods were often inefficient and fragile, they provided necessary workarounds for missing standard features. Ultimately, the industry moved toward better standardization and feature flags to eliminate these precarious practices.
key points
Developers exploited parsing errors, such as the 'star hack' or specific punctuation prefixes, to apply styles only to older versions of Internet Explorer.
Proprietary Microsoft features like CSS Expressions and DirectX-based filters allowed for dynamic styling and visual effects that were not yet part of the official web standards.
Vendor prefixes were originally intended for experimental features but became a burden when developers used them in production, leading browsers to shift toward feature flags.

6 Mixed[consensus]
Commenters generally agree that the era of Internet Explorer 6 and its lack of standards compliance was a period of immense frustration and wasted developer productivity. While they acknowledge that modern browsers have converged on standards, some express concern that this has led to a Namely 'Chrome-first' development approach that occasionally breaks functionality in Firefox or Safari. Overall, the sentiment is one of relief that the industry has moved past the need for browser-specific hacks and vendor prefixes.
top insight
One commenter notes that while IE's box model was non-standard, it was actually more intuitive than the standard W3C box model, leading to the majority of modern developers to adopt 'box-sizing: border-box' to mimic IE's behavior. This highlights how a flawed, non-compliant product can occasionally influence the industry standard through sheer utility.
