    Project mention: What is the best way to develop a frontend using only HTML, CSS, Bootrap, JS w/o frameworks? | | 2022-11-21

    If you do want to use a framework and get up and running quickly, but you still want to know what's going on and have some ability to customize it, maybe you can start with one of the really minimal CSS frameworks like Milligram or Sakura and then add your own modifications.

    I think this doesn't work well even if you have a really large screen. It's doing a style somewhat like but doesn't scale the content to be sure it can fit on the screen, nor center it without having to scroll for sidenotes.

    Just in case the author sees: with the way the sidenotes are specified relative to the parent, this is [probably] better:

    @media (min-width:760px) {

    Project mention: Front-end Guide | | 2022-11-23

    CSS (Cascading Style Sheets) are rules to describe how your HTML elements look. Writing good CSS is hard. It usually takes many years of experience and frustration of shooting yourself in the foot before one is able to write maintainable and scalable CSS. CSS, having a global namespace, is fundamentally designed for web documents, and not really for web apps that favor a components architecture. Hence, experienced front end developers have designed methodologies to guide people on how to write organized CSS for complex projects, such as using SMACSS, BEM, SUIT CSS, etc.

    You could combine styled-components/emotion with something like open-props[0]. You get all the power that comes with CSS and a set of variables to help you create a consistent design. That's how I manage my styling.


  • penthouse

    Generate critical css for your web pages

    Project mention: Critical CSS? Not So Fast | | 2022-09-10

    It is easy with a little automation :). In the build process, adding a step to calculate critical path css helps. This should probably be the last step and run on production post deploy. The calculated CSS is stored in redis which will be appended in the head for subsequent requests. This tool had inspired me to build this process at multiple orgs I have worked with

    Agree on the async JS part but I guess browser makers will solve it soon.

    Project mention: I have been trying to figure out what this website layout is for years. It was really popular with photographers and I finally found a site with it! What is it?! | | 2022-02-19

    That one specifically is the Pushy Menu, just going by what I can see in the source. If you don't need it with the Responsive Design thing, you can do something similar with a couple of frames, like on Sorry I can't help further. I know what you're talking about, I've seen other websites with that exact same sort of menu layout and aesthetic, but I don't think that's because there's a maker for them, just because it's a sort of design a lot of artists tend towards using...
