Ensure that the div element spans the entire width of the screen

Having issues working with the div tag and encountering this problem:

The left side doesn't extend as far as the right side, despite testing in multiple browsers.

Here is the HTML code being used:

<!DOCTYPE html>

<html lang="en">
<head>
    <meta charset="utf-8" />
    <title>@page_title</title>
    <style>
        div {border: 3px solid black; width: 120%; margin: 1.2em; padding: 2em}
    </style>
</head>
<body>
    <div class="div">
        <h1>@page_title</h1>

    </div>
</body>
</html>

Answer №1

Why are you specifying the width as 120%? A block-level element automatically spans 100% of its parent's width, so there is no need to adjust the width in this case.

HTML Code:

<div>
  <h1>@page_title</h1>
</div>

CSS Code:

div {
    padding: 2em;
    margin: 2em;
    border: 3px solid black;
}

Answer №2

The concept of margin in web design dictates the distance an element maintains from its surrounding elements and, in most scenarios, its parent container.

For instance, setting a margin of 1.2em will shift a div away from the left edge by that specific measurement. Initially, eliminate this adjustment.

Furthermore, if you wish for a div to occupy the full width of its containing element (such as the body), utilize width:auto. This attribute ensures that the div's width matches that of its parent, factoring in any margins or padding present on neighboring elements.
