Flexbox, position: fixed, and overflow

I am hoping that someone could help me understand what is going on with my header row with the navbar breaking out of my centering container. Here is my CSS for creating the main centering container, the flex container and other styles:

  background: rgb(153,153,153);
  box-sizing: border-box;
  color: rgb(9,9,9);
  font-family: 'Roboto', sans-serif;
  font-size:18px;
  height: 100%;
}
 a {
   color: rgb(80,89,58);
   text-decoration: none;
 }
 li {
   list-style: none;
 }
 /* Floxbox settings */
 #container {
   border: 1px solid darkblue;
   position: relative;
   margin: 0 auto;
   max-width: 1024px;
 }
#header {
  overflow: hidden;
  position: fixed;
  top: 0;
  height: auto;
  width: 80%;
}
.main {
  margin-top: 100px;
}
.flex-container {
  display: flex;
  align-items: center;
}
.flex-container__column {
  display: flex;
  flex-direction: column;
}
.stylist-logo {
  border: 1px solid darkgray;
  margin-left: 25px;
  margin-top: 15px;
}
.nav {
  border: 1px solid #7A9199;
  margin-left: auto;
  margin-right: 25px;

}
.nav-link {
  padding: 0px 6px;
}```

I have a screenshot showing the main centering container `#container`, and the `#header` with borders surrounding these. I am seeking help understanding why the `navbar` is breaking outside of the main container. ![product-landing-fcc|690x387](upload://i292RrNfQoa3e2J4M9tUGauQLO6.jpeg)

@Gunjan, I’ve added my project to Glitch.

post here link man so i could see your code

This forum will not let me post links. My new user name is @charleyblue-product-land

you add the code in a wrong way

What do you mean? I cloned my app from GitHub using Glitch.

below your profile there is option to create project click new project as it build the index html file css file you have to add there file and for image you can drag and drop in assest file

My index.html and my styles.css files are both there as well as the img assets.

by cilcking the show btn it is suppose to show output

this is wrong way i have send you something just look it

Yes, you will need to click the app directory on the webpage.

Please click on the folder icon on the Show page.

yeah am looking through code enable me to code i ask there for join

As you can see on the output, I have a blue border around the main centering container. Then, I have a red border around the header element. The two elements inside of the header element are stylist-logo and nav

nav is breaking out of the main #container element.

I see that I might want to move my header out of the centering container for this design to work. Would you agree? I see what you have done and will take it from here. Thank you for your help @Gunjan

Well No problem man Happy coding man
