The latest evolution of the Cascading Style Sheets language
+ 1

What is CSS 3?

CSS3 is the latest evolution of the Cascading Style Sheets language and aims at extending CSS2.1. It brings a lot of long-awaited novelties, like rounded corners, shadows, gradients, transitions or animations, as well as new layouts like multi-columns, flexible box or grid layouts. Experimental parts are vendor-prefixed and should either be avoided in production environments, or used with extreme caution as both their syntax and semantics can change in the future.
CSS 3 is a tool in the Languages category of a tech stack.

Who uses CSS 3?

4445 companies reportedly use CSS 3 in their tech stacks, including Glovo, Alibaba Travels, and UpstageAI.

I just finished HTML5 CSS 3 JavaScript Git and I'm looking for the right framework for me. I'm in the middle of React and Angular, so what is the best to learn rn? (the difficulty doesn't matter).

Below is my own professional history to give some context to my current skill set. I have been a front-end dev for 18 years. My tools of choice are:

  • HTML5
  • CSS 3
  • JavaScript
  • WordPress
  • PHP (but not my strongest skill as I don't write it too often)

I first of all would like to become a better and more 'full stack' developer, and I have a business idea that will hopefully allow me to move in this direction. The queries I have will result in which approach I take here. One of the most important aspects to me is the system being 'future proof'. If successful I know I will eventually bring additional developers on board, and they will likely be better developers than me! I want to avoid them having to rebuild the system and would like it to be something that they can just expand and improve on.

The business which I'd like to create is the following (in a nutshell), I have ideas for many more features, but this is how I'd like to begin:

Web-based system for gym management & marketing. Specifically a class-based gym

  1. One-stop shop for a class-based gym owner
  2. Sell memberships
  3. Manage class bookings
  4. Reporting
  5. Automatically generated website
  6. Choose a pre-designed template and amend the content through their dashboard
  7. Marketing
  8. Easily send a newsletter to members
  9. Book a free trial form on the website linked directly to the booking system

Important requirements

  1. One system, one dashboard. I would like the gym owner to have one place to control everything. Members, marketing, and website amendments.
  2. Future proof. These features are the bare minimum and I'd like to keep expanding on the features as time goes on. Things like uploading programming for members, messaging between members and admin, and selling merchandise via the website.
  3. Fast to load & secure. I live in the WordPress world right now, which isn't the fastest or most secure environment. I appreciate there are better ways to develop a system like this, but I'm a little clueless about where to start.
  4. Mobile. The data created should easily communicate with a mobile app that customers will download to manage their memberships and class bookings.

TIA to anybody that can provide some guidance on where to start here.

Hello, it's, good to finally find a community. I am looking for the best route. I just finished studying HTML and I am looking for the best route. I just finished HTML training and I succeeded! so, I want to progress. I have two accredited courses that I have on the shelf ready for learning and don't know which path to take. should I jump right into Python or do I even need to study it first? My other class is CSS 3, should I take that first? Or should I study something else first and come back to it later? Eventually, I would eventually like to be a full-stack developer if I don't run out of time. I am 52 years old. I learned advanced basics when I was 12 but that was a long time ago. And what else do I need to study? I know nothing about anything except basic HTML and looking for a path.

I'm hoping to get some much-needed tech-stack advice. I have been in UX/UI design for ~11 years now. No hands-on programming until very recently, I learned the basics of Python/CSS 3/HTML5/Django/Flask.

I am looking to work in early-stage startups, helping to build tech/software design. Where I would essentially need to wear multiple hats.

The tricky part for me has been understanding which technology I should focus on learning.

I don't really care at all about where the jobs are. I care more about these priorities (in order):

  • Feature-rich / Robust capabilities / Scaling / future-proofing / Security (Is it good tech)
  • Ease of build. (Being a UX/UI guy, I love a good GUI to build with.)
  • Library resources. Would love to skip the easy stuff whenever possible.
  • Strong Dev community.
  • Ability to convert Prototypes to usable code. Figma?
  • Cross-platform capabilities.
  • Monolithic nature. Would love to avoid learning a million different tools.

Basically, I am looking to be enough of a do-it-all type developer, that gets the MVP tech stack far enough along with the company to get funding and get the dedicated resources we would need for whatever the technology is...

Any advice is appreciated! Thanks! - Brian

Hello guys, I created a website for an organization using HTML, CSS 3, and JavaScript. Can I somehow integrate any CMS for this static website? I know of Jamstack but I'm here to ask about other possibilities. Thank you!

Hey everyone, I have a matrix chart drawn in HTML5/CSS 3 dominantly using CSS grid. I would like to add interactive features and am unsure about the best tool. My programming knowledge is limited to 2 semesters of Java in college, so I'd have to learn the language as I go. I am open to anything, but the selected languages would be useful in future projects.

Here are the features I am attempting to add to the site linked as my blog:

  • Assign over 120 attributes each to over 400 elements (probably in a DB)

  • Procedurally position elements in a matrix chart based on user-inputted filters (filtering and searching)

  • Procedurally position matrix elements based on attributes weighted by user-input

  • Change style of elements based on user input (highlighting)

  • Allow saving matrix chart states to be revisited or shared

  • Provide a user-friendly interface for users to submit the above input

  • Build several columns or matrices that are separate but related and seamless to the viewer
