为什么我的导航栏对齐水平和垂直媒体查询？

Question

I am trying to create a navbar in pure html/css that at less than 600px width is horizontal with a horizontal set of links inline (no bullet points). At more than 600px width, I want a vertical navbar with a vertical list.

However, my horizontal version keeps giving me a vertically stacked set with bullet points and my vertical version has the word 'links' inline with 'paragraph' when I want it underneath.

I'm at a fault to see what I'm doing wrong. I tried scrubbing it out and starting again which worked until I put in my media query and it all went wrong again. Any help appreciated.

<header>
  <nav id="navbar">
    <h1>HTML Basics</h1>
    <ul>
      <li>Documents</li>
      <li>Headings</li>
      <li>Paragraph</li>
      <li>Links</li>
      <li>Images</li>
    </ul>
  </nav>
</header>

#navbar{
  background: red;
  width: 100%;
  height: 20%;
  margin: auto;
  position: fixed;
  display: inline;
  float: top;
  top: 0;
  left: 0;
}

@media screen and (min-width:600px){
  #navbar{
  background: red;
  width: 22%;
  height: 100%;
  margin: auto;
  position: fixed;
  display: block;
  top: 0;
  left: 0;
}


li{
  list-style: none;
 padding-right: 20px;
  padding-bottom: 20px;
  display: inline-block;
  margin-left: 10%;
  float: left;
    font-family: 'Nunito Sans', sans-serif;
  text-decoration: none;
  font-size: 12px;
}

@media only screen and (min-width:600px){
  li{
  list-style-type: none;
  display: block;
  font-family: 'Nunito Sans', sans-serif;
  text-decoration: none;
  font-size: 20px;
}
}

li:hover{
  color:#911f32;
  font-size: 18px;

}

Answer 1

You're missing a closing curly brace in your first Media Query. Try this:

#navbar {
  background: red;
  width: 100%;
  height: 20%;
  margin: auto;
  position: fixed;
  display: inline;
  float: top;
  top: 0;
  left: 0;
}

@media screen and (min-width:600px) {
  #navbar {
    background: red;
    width: 22%;
    height: 100%;
    margin: auto;
    position: fixed;
    display: block;
    top: 0;
    left: 0;
  } // <-- NOTE! This curly brace was missing...
}


li {
  list-style: none;
  padding-right: 20px;
  padding-bottom: 20px;
  display: inline-block;
  margin-left: 10%;
  float: left;
  font-family: 'Nunito Sans', sans-serif;
  text-decoration: none;
  font-size: 12px;
}

@media only screen and (min-width:600px){
  li {
    list-style-type: none;
    display: block;
    font-family: 'Nunito Sans', sans-serif;
    text-decoration: none;
    font-size: 20px;
  }
}

li:hover{
  color: #911f32;
  font-size: 18px;
}

Answer 2

You had some errors in there:

• You used min-width both times instead of min/max

• For the horizontal version you need to allow full width (100%)

• You forgot a closing curly brace

• There is no float: top; (but that has no effect anyway)

 #navbar { background: red; width: 100%; height: 20%; margin: auto; position: fixed; display: inline; top: 0; left: 0; } @media screen and (max-width:600px) { #navbar { background: red; margin: auto; position: fixed; display: block; top: 0; left: 0; } li { list-style-type: none; padding-right: 20px; padding-bottom: 20px; display: inline-block; margin-left: 10%; float: left; font-family: 'Nunito Sans', sans-serif; text-decoration: none; font-size: 12px; } } @media only screen and (min-width:600px) { #navbar { width: 20%; height: 100%; } li { list-style-type: none; display: block; font-family: 'Nunito Sans', sans-serif; text-decoration: none; font-size: 20px; } } li:hover { color: #911f32; font-size: 18px; }

 <header> <nav id="navbar"> <h1>HTML Basics</h1> <ul> <li>Documents</li> <li>Headings</li> <li>Paragraph</li> <li>Links</li> <li>Images</li> </ul> </nav> </header>

1. Add style for your list-item element (600px and down).
2. Comment unnecessary style (600px and up).

Look at CSS code below.

 #navbar{ /* ... */ } /* === Add this code */ li { list-style-type: none; display: inline-block; } @media screen and (min-width:600px){ #navbar { /* ... */ } /* === You don't need "display: inline-block" and "float: left" */ li { list-style: none; padding-right: 20px; padding-bottom: 20px; /* display: inline-block; */ margin-left: 10%; /* float: left; */ font-family: 'Nunito Sans', sans-serif; text-decoration: none; font-size: 12px; } /*...*/
