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; }
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>
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; }
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; }
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.
