justify-content property behavior-CodePudding

I'm practicing flexbox and I need help to understand why nav ul elements are displayed as flex with justify-content: space-between properties are not stretching and remain stuck to each other.

I expect the ul items to be gradually distributed within header-nav__ul container, which I allowed to be stretched through flex: 1 1 auto. Still, I'm not able to achieve the result.

The problem is that the nav has no width.
Imagine you have a container with width:500px and it has 2 children with width:250px, you can space the children around, but they have no space to move, that's why it appears not working but it is.
So try giving the header-nav a flex-grow:1; to make it fill the remaining space of its container, and the header-nav__ul a width:100%; to give it the full width of its container:

.header-nav{
    /* ... the old code */
    flex-grow:1;
}
.header-nav__ul {
    /* ... the old code */
    width:100%;
}

CodePudding user response：

Don't get me wrong. The parent element, use are using display: block. Use flex first. The other thing is the margin:0 auto which is taking the entire space left and right. So, remove it.

Look at this code.

Let me know if it helps.
