'how to move a text to the right side of the page

I'm trying to move the navbar contents to the right side of the page but it's not aligning with the navbar title.

* {
    margin: 0;
    padding: 0;
    font-family: Arial, Helvetica;
}
header li {
    list-style: none;
    float: right;
    display: inline;
    padding: 20px;
   padding-left:3px;
}
header {
  justify-content: space-between;
  align-items: center;
   box-shadow: 0 1px 8px #ddd;
  
}
<header>
<h1> Dev101 </h1>
  <nav>
 <ul>
          <li><a href="#">About</a></li>
          <li><a href="#">Services</a></li>
          <li><a href="#">Contact</a></li>
 </ul>
  </nav>
 </header>


Solution 1:[1]

You can add a flex to the header:

header {
  display: flex;
  justify-content: space-between;
  align-items: center;
  box-shadow: 0 1px 8px #ddd;
}

Solution 2:[2]

Remove the float. float's are deprecated. In order for justify-content: space-between; to work you need to use display: flex; on the same element.

* {
  margin: 0;
  padding: 0;
  font-family: Arial, Helvetica;
}

header li {
  list-style: none;
  display: inline;
  padding: 20px;
  padding-left: 3px;
}

header {
  display: flex;
  justify-content: space-between;
  align-items: center;
  box-shadow: 0 1px 8px #ddd;
}
<header>
  <h1> Dev101 </h1>
  <nav>
    <ul>
      <li><a href="#">About</a></li>
      <li><a href="#">Services</a></li>
      <li><a href="#">Contact</a></li>
    </ul>
  </nav>
</header>

Without using any padding , basically making it responsive , try to avoid using px in your websites as it is not good for responsiveness .

Instead use % , rem , em .

* {
  margin: 0;
  padding: 0;
  font-family: Arial, Helvetica;
}

header li {
  list-style: none;
  display: inline;
}
header li a{
  text-decoration: none;
}
header li a:hover{
  text-decoration: underline;
}
 

header {
  display: flex;
  justify-content: space-between;
  align-items: center;
  box-shadow: 0 1px 8px #ddd;
}
header nav{
  width:40%;
}
header nav ul{
  display: flex;
  justify-content: space-evenly;
  align-items: center;
}
<header>
  <h1> Dev101 </h1>
  <nav>
    <ul>
      <li><a href="#">About</a></li>
      <li><a href="#">Services</a></li>
      <li><a href="#">Contact</a></li>
    </ul>
  </nav>
</header>

Just use float to align nav to the right

HTML:

<header>
  <h1>Dev420</h1>
 <nav>
   <ul>
       <li><a href="#">About</a></li>
       <li><a href="#">Services</a></li>
       <li><a href="#">Contact</a></li>
   </ul>
 </nav>
</header>

CSS:

nav{
   float: right;
}
