Hey :)
I'm back after a long break, It's a very good experience to talk with all of you again.

I bought up my first domain for my portfolio and blog(I'm not leaving DEV). I was really busy all those days and I just pointed out the domain to my twitter account, I was really seeking out time to design my portfolio but I was a lot busier than ever before, I was working really hard to get things stable in my company(startup). I explored a lot of things, and I have a lot of stories to tell you.

I took a break from my work to fresh up myself and I started designing my website straightforward. I will explain all the things in upcoming posts but this post is just about a problem that I experienced and I have a solution for you all.

MEME

I created a fixed navigation bar like this by applying the position property on the main navigation bar container:

   nav{
     position: fixed;
     top: 0px;
  }

Now I want to get a box-shadow and a border-bottom when someone scrolls the page.

Solution:

• First Create a CSS class with these styles applied, so we just have to toggle the class.

  .scroll {
    box-shadow: 1px 2px 18px rgba(0, 0, 0, 0.1);
    border-bottom: 2px solid #257942;
  }

• create a data property to save the scroll postion.

  data(){
      return{
        scrolled: false
      }
    },

• Then We have to play with event listeners to get the required information, we have to run the function every time, to record the scroll position.:

methods: {
  handleScroll () {
    this.scrolled = window.scrollY > 0;
  }
},
created () {
  window.addEventListener('scroll', this.handleScroll);
},
destroyed () {
  window.removeEventListener('scroll', this.handleScroll);
}

• We can now apply the dynamic class like this:

  <nav :class="scrolled ? 'scroll' : ''"> </nav>

That's all, It's the easiest way to bind window events to your app and components.

Final Solution:

Thanks, for reading this post. This is my first post after a long time, so I lost my momentum and style but I hope I can grab it again and you'll hear from me again soon!

Bye :)
