lessonThree: learning HTML and CSS

This session is going to be verbose. This means there are fewer concepts and more keyword-based coding. This is the nature of HTML/CSS, that you need to know the right keyword.

Therefore, we will do an online search to find out what we need.

Less to understand, more to do in this session.

how does this work in the industry?

The session is akin to how it works. You get a design, generally in Figma, sketch, etc. And then you have to replicate that design using CSS.

Where new developers go wrong sometimes is not using the right semantic element for components, and thus, we'll cover that topic first.

what you can do?

  1. Watch and take notes.
  2. Use an online search to look for the CSS properties I am using, or the HTML tag I am using to know more about it.
  3. Try and code some of these pieces with me. I'll go slow.
  4. Understand the major concepts. There are a few concepts that are there in HTML/CSS which I'll be explaining, look out for that.

We get to usual programming next week.

assignments for markFour and markFive


Host your portfolio. Put all your projects and Twitter, LinkedIn, and other details.

Do what I did in the live workshop and host your own portfolio with your details.

markFive -

  • Have a Blog listing page similar to a project listing page**.** For example, see tanay’s blog listing page
  • Your blog listing page should list down all your blogs with either link to your Hashnode, etc. blogs or your blog reading pages, with a call-to-action button for READ MORE. Example tanay’s blog page.
