Greetings fellow developer, how are you? 👋🏼
Hope you all are doing great 🙂

Today, I'm gonna talk about CSS! Almighty CSS, every developer's worst nightmare. OK, maybe not the worst but let's admit it, CSS is wearisome if you are a beginner who does not have much experience writing CSS.

So I just had a wonderful session with the CSS Wizard, Kuhagra Gour. For those of you who don't know him, he's the creator of CSS Battle, Web Maker and more. The session was a part of NeoG Camp's guest lecture series where we get the chance to interact, learn and clear our doubts directly with the industry experts.

We covered a lot of topics and discussed tons of problems that students face while writing CSS.
Now as we covered a lot of ground it's not possible for me to write each and everything that we discussed but I can provide you with some tips which may be very useful to you if you struggle while writing CSS or if you are just a beginner in front-end development.

Let's Start,

• When developing applications, always try to do a mobile-first approach. And then, later on, optimize it for desktop.

• Try not to nest classes while writing CSS inside the stylesheet, writing CSS for one class only will help.
  

  /* BAD */
  .conainer .paragraph .hightlight {
    background-color: gray;
  }

  /* GOOD */
  .highlight {
    background-color: gray;
  }

• Keep the Magic Numbers & Values inside CSS variables (such as colors, margin, padding, font-size, etc)

 :root {
   /* COLORS */
   --primary-color: #0B5ED7;
   --secondary-color: #5C636A;
   --dark-color: #1C1F23 ;
   --info-color: #0EA5E9;
   --link-color: #1D4ED8;
   /* SPACING */
   --padding-one: 1rem;
   --padding-two: 2rem;
   --padding-three: 3rem;
 }

• The above point will also help you in creating themes based on your current CSS, just change the variable values and VOILA! there you have yourself a new theme.

• Always keep spacing consistent.

• Use Vanilla CSS as much as possible.

• Try not to use "px" for spacing and sizing, instead use "rem" and "em" for responsiveness ("rem" is more preferred).
  

  /* Avoid */
 .container {
  padding: 48px;
 }
  /* Use */
 .container {
  padding: 3rem;
 }

• Use a consistent naming convention for your classes (for better DX).

• While writing an app keep in mind to give equal importance to both UX and DX.

• While approaching a complex design, first take your time and identify your components

  • Components that are not going to be in normal flow i.e., components having position: absolute and position: fixed;
  • Container components which are uni-directional will use display: flex;
  • Container components which are bi-directional will use display: grid;

And then plan your approach accordingly.

That's all for now!
I hope this helps somebody.

Thank You ✌🏼
Happy Coding 🧡
