Why Isn't `body { margin: 0; }` Removing My Logo's Top Margin?

Troubleshooting Margin Removal in CSS

When encountering margin issues in web development, novice programmers may wonder if the following CSS rule is appropriate:

body {
  margin: 0;
}

Copy after login

Problem Statement

Applying the above code to eliminate the spacing between the browser's top and the "logo" text proves unsuccessful. The following code is available for reference on jsbin:

<head>
  <style>
    body {
      margin: 0;
    }
  </style>
</head>

<body>
  <div class="logo">
    <h1>Logo</h1>
  </div>
</body>

Copy after login

Answer

While the provided CSS rule is intended to remove the body's margin, it may not be the ideal solution in this scenario. Using a global reset like this:

* {
  margin: 0;
  padding: 0;
}

Copy after login

can have unintended consequences. In this particular instance, the "logo" headline's margin protrudes beyond its parent element due to the absence of padding in the parent.

A more targeted approach is recommended:

.logo {
  padding: 10px;
  margin: 0;
}

Copy after login

Setting the parent's padding ensures that the "logo" margin remains within the parent. Removing all margins and paddings can have unforeseen effects, making it preferable to focus on the specific element rather than resorting to a global reset.
