The HTML width of 100% extends beyond the boundaries of the page

Having limited experience with HTML and CSS, I'm encountering an issue with setting the width to 100%. It seems to exceed the browser borders. Can someone check out the example below? Should I slightly decrease the width percentage, or could there be flaws in my code causing this problem?

I've come across other posts discussing the 100% width, but none of them have provided much help. Here's the example I created: http://jsfiddle.net/gj53jbz9/


 body {
    font-size: 15px;
    margin: 0px;
    background-color: lightgrey;
}

#header {
    padding: 30px;
    width: 100%;
    height: 250px;
    background-color: grey;
}

#name {
    padding: 5px;
    font-size: 25px;
    float: left;
}

#navbar {
    float: right;
    text-align: right;
}

#navbar a {
    background-color: black;
    display: inline-block;
    width: 120px;
    text-align: center;
    padding: 10px 0px;
    text-decoration: none;
    color: lightgrey;
}

#title {
    clear: both;
    text-align: center;
    padding-top: 100px;
    font-size: 45px;
}

#content {
    text-align: center;
    width: 80%;
    margin: 0px auto;
}
<div id=header>
    <div id=name>Name</div>
    <div id=navbar>
        <a href="page1.html">Link1</a>
        <a href="page2.html">Link2</a>
    </div>
    <div id=title>Insert title here</div>
</div>
<div id=content>
    <h3>Age of aggression</h3>
    <p>We drink to our youth, to days come and gone. For the age of aggression is just about done. We'll drive out the Stormcloaks and restore what we own. With our blood and our steel we will take back our home.</p>
    <p>Down with Ulfric! The killer of kings! On the day of your death we will drink and we'll sing. We're the children of Skyrim, and we fight all our lives. And when Sovngarde beckons, every one of us dies! But this land is ours and we'll see it wiped clean. Of the scourge that has sullied our hopes and our dreams!</p>
</div>

Answer №1

The reason for this issue is that both the width and padding are applied to the same element. By default, padding is added on top of the specified width, effectively increasing the total width by twice the padding size.

#content{
  padding: 20px;
  width: 80%;
}

To resolve this, you can either remove the padding from the outer element and apply it to an inner element with no width set, or use the following CSS property:

box-sizing: border-box;

By using 'box-sizing: border-box', the width calculation will include the padding, ensuring a more accurate layout. :)

Answer №2

Check out this section of your coding:

        #header{
          padding: 30px;
          width: 100%;
          height: 250px;
          background-color: grey;   

This code specifies that the width of #header should be 100% with a 30px padding. Since padding is not included in the width, the actual total width ends up being 100% + 60px. To ensure that it fits within the page, you must subtract 60px (30px on each side) from the 100% width. This adjustment can easily be made using CSS:

        #header{
          padding: 30px;
          width: calc(100% - 60px);
          height: 250px;
          background-color: grey;   

Answer №3

After some experimentation, it appears that removing margin: 0px; from the styles within body {} makes the code work as intended. The reasons behind this behavior remain unclear to me.

Answer №4

By default, HTML elements determine their dimensions based solely on the content, disregarding padding, borders, and margins. If you want to change this behavior, simply add the following CSS rule:

box-sizing: border-box;

With this rule, calculations will now include padding and borders. It's recommended to apply this rule to all elements on your page like so:

* {
    box-sizing: border-box;
}

Answer №5

Each HTML element comes with its own set of default values. For a detailed list, you can refer to the following link: https://www.example.com/default-values-for-html-elements

If you want to reset all elements' margin and padding to zero, you can use the following CSS code:

*{margin: 0; padding: 0}

Answer №6

Avoid adding padding to both the left and right sides of your header division.

Instead, include some margin for the name and navigation bar divisions

similar to this:

#header {
    padding: 30px 0px;
    width: 100%;
    height: 250px;
    background-color: grey;
}

#name {
    padding: 5px;
    font-size: 25px;
    float: left;
    margin-left: 40px;
}

#navbar {
    float: right;
    text-align: right;
    margin-right: 40px;
}

Answer №7

The reason for this is that the padding is adding to the total width of 100%.

To address this issue, consider using the box-sizing property in your CSS code:

#main-content{
    padding: 20px;
    width: 100%;
    height: 300px;
    background-color: blue; 
    box-sizing: border-box;
}

Answer №8

The issue is being caused by Header.Width=100% and Header.Padding=30px.

By setting both the width to 100% and adding a padding of 30px, you are essentially telling the browser to make the header take up 100% of the width plus an additional 30px from the padding.

To resolve this, consider moving the width property to the body element so that the entire page utilizes 100% of the available space. This adjustment should solve the problem.

margin-left: 0px;
margin-right: 0px;
width: auto;
position: relative;
