Answer 1

有2种方法可以解决此问题。

方法1：

尝试将left: 0px;添加到.navbar选择器中。

这是您的代码：

.navbar {
  width: 100%;
  background-color: #555;
  overflow: hidden;
  position: fixed;
  top: 0;
  padding: 0px;
  left: 0px;
  scroll-behavior: smooth;
}

.navbar a {
  float: left;
  text-align: center;
  padding: 12px;
  color: white;
  text-decoration: none;
  font-size: 17px;
}

.navbar a:hover {
  background-color: #000;
}

.active {
  background-color: #4CAF50;
}

@media screen and (max-width: 600px) {
  .navbar a {
    float: none;
    display: block;
  }
}

<div class="navbar">
   <a class="active" href="#about">About Me</a>
   <a href="#skills">Skills</a>
   <a href="#schedule">Schedule</a>
   <a href="#contact">Contact</a>
</div>

方法2：

将margin: 0;添加到body选择器中。

这是您的代码：

body {
   margin: 0;
}
    
.navbar {
    width: 100%;
    background-color: #555;
    overflow: hidden;
    position: fixed;
    top: 0;
    padding: 0px;
    scroll-behavior: smooth;
}

.navbar a {
    float: left;
    text-align: center;
    padding: 12px;
    color: white;
    text-decoration: none;
    font-size: 17px;
}

.navbar a:hover {
    background-color: #000;
}

.active {
    background-color: #4CAF50;
}

@media screen and (max-width: 600px) {
    .navbar a {
      float: none;
      display: block;
    }
}

<div class="navbar">
  <a class="active" href="#about">About Me</a>
  <a href="#skills">Skills</a>
  <a href="#schedule">Schedule</a>
  <a href="#contact">Contact</a>
</div>

Answer 2

更新更新CSS代码后。 body中的填充会引起额外的空间。

body {
    position: relative;
    top: 30px;
    font-family: 'Cabin Condensed';
    font-size: 18pt;
    background-color: #f2f2f2;
    text-align: left;
    padding: 10px; /*Set it to 0*/
    margin: 0;
}

body标签具有默认边距。将其重置为0；

body {
margin:0;
}
.navbar {
    width: 100%;
    background-color: #555;
    overflow: hidden;
    position: fixed;
    top: 0;
    padding: 0px;
    scroll-behavior: smooth;
  }
.navbar a {
    float: left;
    text-align: center;
    padding: 12px;
    color: white;
    text-decoration: none;
    font-size: 17px;
  }
.navbar a:hover {
    background-color: #000;
  }
.active {
    background-color: #4CAF50;
  }
@media screen and (max-width: 600px) {
    .navbar a {
      float: none;
      display: block;
    }
  }

<div class="navbar">
 <a class="active" href="#about">About Me</a>
 <a href="#skills">Skills</a>
 <a href="#schedule">Schedule</a>
 <a href="#contact">Contact</a>
</div>
