Tailwind CSS vs Traditional CSS: Efficiency and Speed

I’ve been working with CSS for years, but I recently got a reality check. After almost 2 years of development with Tailwind CSS, I had to maintain a project built with "pure" CSS (SASS + BEM methodology). I quickly realized how much I’ve adapted to the utility-first workflow, where styles are applied directly via predefined classes. The experience was eye-opening: I found myself spending more time managing selector hierarchy and naming conventions than actually building the interface. The cognitive load of switching between files and fighting specificity felt like a significant bottleneck. While I still value the foundations of CSS (and leaner HTML files, with cleaner tags), the efficiency of a utility-first approach is hard to ignore: 🚀 Rapid UI Development: Build and iterate on interfaces significantly faster by composing utilities directly in the markup. 🧠 Reduced Cognitive Load: Eliminates the need to invent semantic class names for every single element. 🎨 Design Consistency: Built-in spacing and color scales ensure a professional look without manual "pixel-pushing." Tailwind allows me to "style as I think." It doesn't replace the need to understand CSS, but it certainly changes the speed at which we can deliver high-quality results. For the developers out there: Do you also feel a "speed gap" when returning to traditional CSS, or do you still prefer the complete separation of styles? #webdevelopment #tailwindcss #frontend #css

I'm coming from the opposite place honestly. I can settle in to a TW utility-first shop just fine if needed but I don't ever do my own personal or OSS projects with it. One thing I'd say which I think is a fair neutral point: if you ARE using Tailwind, you can certainly abstract those utilities into their own abstractions when you see 3+ usages that are duplicates. Case study: We used Boostrap's utilities (very much in a same manner to TW) and these guys had like 20+ sidepanels where, for some reason, there were direct descendent elements that had to have `h-100`. Inevitably, someone would forget to place the h-100 on the parent element, and, we all know what happens next. It wasn't terribly hard to debug, but, was a PITA and I went ahead and abstracted it into some sort of sidebar-title. Regressions gone. It's not a panacea but good judgment and discretion is always required.

I use Bem in CMS development and I use global variables for things like colors, font sizes, border radius, padding, widths etc… and then component CSS is contained within each module… I find it easy to maintain with great readability

BEM is so old school 🤣 jokes aside, I totally agree about the cognitive load while working with CSS

The only thing I disagree here is the necessity to "invent semantic class names" like it is really hard to do. With CSS/SCSS modules I normally write small class names, semantic, but with a lot of quick solutions. Every UI element I have that has a "title" have a high chance to have a .title class, not: cardTitle or myComponentTitle, just .title. For the file switch, it depends on the framework/lib I'm working with. On Astro and Vue projects is the same file so it does not have an impact in it.
