CSS Is Harder Than Assembly

A lot of people think Casey is joking about CSS being harder than ASM. No, it's actually unironically true. Web spec is way more complex than any mainstream ISA you might ever need. If you've mastered the dark corners of flexbox and grid, if you know subtle differences in how browser engines treat font sizes, if you ever worked on reducing CLS and optimizing LCP - x86 assembly will be a piece of cake for you as soon as you learn a little bit of bit math. I swear to you, mental overhead of being closer to the hardware is orders of magnitude lower!

A screenshot shows Casey Muratori wearing headphones and speaking, beneath a long caption arguing that CSS and web specifications are more mentally complex than x86 assembly. The joke exaggerates the difficulty of modern web development and contrasts browser layout quirks with low-level programming; it is used as a reaction when someone complains about CSS or praises the simplicity of assembly.
