Create a stylish design with Bootstrap 3.0 featuring a full-width color background and compact columns perfectly centered on the

As I ventured into creating a business theme with stripes, akin to the one developed by W3Schools and accessible here, I encountered a particular challenge. The layout consisted of horizontal sections with varying background colors.

My main concern was that the columns in Services, Portfolio, and Pricing extended across the entire width of the page, which didn't seem visually appealing. Specifically, the three pricing boxes felt too wide and should have been more centered. Let's focus on these pricing boxes for the following questions.

To address this issue, I set out to narrow down and center these pricing boxes while preserving the alternating full-width background color scheme. Here are three approaches I considered:

1) Nesting a Container within a Fluid-Container:

<div id="pricing" class="container-fluid">
    <div class="container">
        <div class="row">
            <div class="col-sm-4 col-xs-12">
                BlaBlaBla
            </div>
            ...
        </div>
    </div>
</div>

2) Implementing CSS and HTML Adjustments:

.fixed-width {
    display: inline-block;
    float: none;
    width: 300px;
}
.row-centered {
    text-align: center;
}

-

<div id="pricing" class="container-fluid">
    <div class="row row-centered">
        <div class="col-sm-4 col-xs-12 fixed-width">
            BlaBlaBla
        </div>
        ...
    </div>
</div>

3) Using 3x col-sm-2 with Empty Columns:

Maintaining the fluid-container layout, I substituted three col-sm-4 with an empty col-sm-3, three col-sm-2, and concluded with another empty col-sm-3 (totaling 12 columns).


4) Utilizing 3x col-sm-2 with offset-3 for Centering:

In place of three col-sm-4, I opted for one col-sm-2 col-sm-offset-3, followed by two col-sm-2 (though not adding up to 12, the centering is achieved with offset).**


However, both options (3) and (4) presented issues whereby shrinking the browser window led to the boxes becoming too small before wrapping onto the next line (resulting in text spillover). Additionally, when utilizing container instead of container-fluid in (4), the boxes appeared excessively narrow even in fullscreen mode.

What would be the most effective approach to tackle this? It seems like a common obstacle faced by many crafting business websites, yet after hours of online research, I couldn't locate a satisfactory solution.

Appreciate your insight,

Here is my recommended solution for applying a background image or color across the full width using CSS.

CSS (formatted for illustration and fixed width)

.content{
    padding:20px;
    border: 1px solid #269abc;
    background:#d6ec94;
}
[class*="col-"] {
    padding-top:10px; /* 15px side paddings automatically applied */
    padding-bottom:10px;
    border: 1px solid grey;
    background: transparent;
}
.fixed-width {
    display:inline-block;
    float:none;
    width: 300px;
}

The key aspect here is the use of the fixed-width class, following approach (2). The other styles provided are merely for demonstration purposes.

CSS (background image)

#one {
    background-image: url([insert-url]);
    background-repeat: no-repeat;
    background-size: contain;
    height:500px;
}

The crucial element in this snippet is the background-size: contain property. It ensures that the background image fills the section while maintaining its ratio.

CSS (background color)

#two {
    background-color: grey;
    height:500px;
}

The background-color property requires no additional adjustments to work effectively.

HTML

<section id="one">
    <div class="container">
        <div class="row text-center">

            <div class="col-sm-4 fixed-width">
                <div class="content">HERE</div>
            </div>

            <div class="col-sm-4 fixed-width">
                <div class="content">HERE</div>
            </div>

            <div class="col-sm-4 fixed-width">
                <div class="content">HER</div>
            </div>

        </div>
    </div>
</section>

By enclosing the content within a <section> tag, you can achieve a consistent background image or color spanning the full width of the page.

Bootstrap Breakdown:

Col-lg pertains to large screens, Col-sm is for small screens, Col-md caters to medium devices, Col-xs targets small screens.

For optimal display across browsers, we can utilize all classes. In my experience, col-lg-offset-3 works well for large screens, while the remaining screens should be used without an offset, as shown below:

Styling UL List:

<style>
   ul{
     margin:0;padding:0;
     text-align:center;
    }
   ul li
  {
     display:inline-block;
     text-align:center;
     width:300px;
   }
</style>
    <ul>
       <li>box1</li>
       <li>box2</li>
       <li>box3</li>
    </ul>

This ensures that no matter the screen size, the list will be centered on the screen.

Alternative Format:

<div class="container">
   <div class="row text-center"> 
    <div class="col-lg-offset-3 col-lg-2 col-sm-4 col-md-4 col-xs-12">content box..</div>
    <div class="col-lg-2 col-sm-4 col-md-4 col-xs-12">content box..</div>
    <div class="col-lg-2 col-sm-4 col-md-4 col-xs-12">content box..</div>
  </div>
</div>

We should tailor our use of classes to suit our business requirements. Consider experimenting with various offset classes like col-sm-offset-, col-md-offset- for optimal layout design and alignment.

Answer №3

<div class="col-sm-4 col-xs-12">

One of the crucial lines here is the col-sm-4, which dictates that on small screens and above, it should occupy 4 out of the 12 bootstrap columns. To experiment with a different layout, consider changing this to col-sm-3 for 3 out of 12 bootstrap columns. Here's how it looks in the provided source code snippet:

 <div class="col-sm-3 col-xs-12">
  <div class="panel panel-default text-center">
    <div class="panel-heading">
      <h1>Basic</h1>
    </div>
    <div class="panel-body">
      <p><strong>20</strong> Lorem</p>
      <p><strong>15</strong> Ipsum</p>
      <p><strong>5</strong> Dolor</p>
      <p><strong>2</strong> Sit</p>
      <p><strong>Endless</strong> Amet</p>
    </div>
    <div class="panel-footer plan">
      <h3>$19</h3>
      <h4>per month</h4>
      <button class="btn btn-lg">Sign Up</button>
    </div>
  </div>
