After using a boilerplate that included normalize.css, I noticed that there was always a strange gap above the body element. Despite searching through the normalize.css file, I couldn't find the reason for this issue. However, when I tested my CSS without normalize.css, everything worked as expected.
To provide a visual explanation, I have included an image below. The white bar on the left side signifies the unwanted gap that appears when using normalize.css, while the right side shows the desired result achieved with my own minimal CSS:
For a demonstration, please visit:
Here is a snippet of the HTML code:
<body>
<div id="container">
k
</div>
</body>
And here is a sample of the CSS used:
div#container {margin: 1em;background:silver}
body { background: red;}
If anyone can shed light on where this gap is originating from and offer suggestions on how to resolve it, I would greatly appreciate it. Thus far, my search within the normalize.css file has been unsuccessful in pinpointing the cause.
UPDATE: Additionally, I have attached another image illustrating the margin around the div element, though the focus remains on identifying the mysterious gap at the top.
