Increasing font size without moving other text

问题

I'm learning HTML and CSS, I have searched this question but I didn't find a solution which worked for me.

So in my navigation bar, when the user hovers their mouse over a piece of text the size increases but also moves the other pieces of text. I want the size to increase but not move the other pieces of text.

MY WEBSITE

.nav {
    margin-top: 0px;
    height: 40px;
    width: 600px;
    background: white;
}
.nav ul {
    display: inline-block;
    margin: 0;
    padding: 0;
}
.nav ul li {
    list-style: none;
    display: inline;
}
.nav ul li a {
    text-decoration: none;
    float: left;
    display: block;
    padding: 10px 20px; 
    color: black;
    font-family: ProximaNova;
    font-size: 18px;
}
.nav ul li a:hover {
    color: #D46300;
    font-size: 22px;
}

 <div class="nav">
            <ul>
                <li><a href="news.html">News</a></li>
                <li><a href="servers.html">Servers</a></li>
                <li><a href="donate.html">Donate</a></li>
                <li><a href="bans.html">Bans</a></li>
                <li><a href="support.html">Support</a></li>
            </ul>
        </div>

Is this what you're looking for?

.nav {
  margin-top: 0px;
  height: 40px;
  width: 600px;
  background: white;
}

.nav ul {
  display: block;
  margin: 0;
  padding: 0;
  position: relative;
}

.nav ul li {
  list-style-type: none;
  display: inline-block;
  width: 20%;
  padding: 0;
  margin: 0;
  float: left;
  text-align: center;
}

.nav ul li a {
  text-decoration: none;
  display: block;
  width: 100%;
  height: 100%;
  line-height: 40px;
  color: black;
  font-family: ProximaNova;
  font-size: 18px;
  transition: color .3s cubic-bezier(0.55, 0, 0.55, 0.2) , font-size .3s cubic-bezier(0.55, 0, 0.55, 0.2) ;
}

.nav ul li a:hover {
  color: #D46300;
  font-size: 22px;
}

<center>
  <div class="nav">
    <ul>
      <li><a href="news.html">News</a></li>
      <li><a href="servers.html">Servers</a></li>
      <li><a href="donate.html">Donate</a></li>
      <li><a href="bans.html">Bans</a></li>
      <li><a href="support.html">Support</a></li>
    </ul>
  </div>
</center>

As a matter of fact, changing font size is NOT recommended for text animations, as most of the times animation is jerky. Here's an example using scale:

.nav {
      margin-top: 0px;
      height: 40px;
      width: 600px;
      background: white;
    }
    .nav ul {
      display: block;
      margin: 0;
      padding: 0;
      position: relative;
    }
    .nav ul li {
      list-style-type: none;
      display: inline-block;
      width: 12%;
      padding: 0;
      margin: 0;
      text-align: center;
    }
    .nav ul li a {
      text-decoration: none;
      text-rendering: geometricPrecision;
      position: relative;
      display: block;
      width: 100%;
      height: 100%;
      line-height: 40px;
      color: black;
      font-family: ProximaNova;
      font-size: 18px;
      transition: transform .3s cubic-bezier(0.55, 0, 0.55, 0.2) , color .3s cubic-bezier(0.55, 0, 0.55, 0.2);
      transform-origin: 50% 30%;
    }
    .nav ul li a:hover {
      color: #D46300;
      transform: scale(1.3);
    }

<center>
  <div class="nav">
    <ul>
      <li><a href="news.html">News</a>
      </li>
      <li><a href="servers.html">Servers</a>
      </li>
      <li><a href="donate.html">Donate</a>
      </li>
      <li><a href="bans.html">Bans</a>
      </li>
      <li><a href="support.html">Support</a>
      </li>
    </ul>
  </div>
</center>

Here's the fiddle. Feel free to tweak it to your liking.

This happens because the width of the elements change when the size gets bigger. One solution is to give li an explicit width:

.nav ul li {
    list-style: none;
  float: left;
  width: 40px;
    padding: 10px 20px; 
}
.nav ul li a {
    text-decoration: none;
    display: block;
    color: black;
    font-family: ProximaNova;
    font-size: 18px;
  height: 100%;
  width: 100%;
}
