Creating a responsive layout with two nested div elements inside a parent div, all styled

I'm currently facing an issue with using padding in my CSS to make the two divs inside a parent div responsive at 50% each. However, when combined, they exceed 100%. I suspect this is due to the padding, but I'm unsure how to resolve it.

.columns {
max-width:100%;
width:100%;
display:inline-block;
text-align:left;
}
.col1 {
width:50%;
float:left;
padding-left:100px;
}
.col2 {
width:50%;
float:right;
padding-right:100px;
}

Here is the HTML code:

    <div class="columns">
        <div class="col1">
        </div>
        <div class="col2">
        </div>
    </div>

By default, when using the box model, padding and border will cause an element to exceed its specified width. To prevent this outward expansion and keep the paddings/borders contained within the element, apply box-sizing: border-box;

.sections {
  max-width: 100%;
  width: 100%;
  display: inline-block;
  text-align: left;
}

.section1 {
  width: 50%;
  float: left;
  padding-left: 100px;
}

.section2 {
  width: 50%;
  float: right;
  padding-right: 100px;
}

.section1,
.section2 {
  box-sizing: border-box;
}

<div class="sections">
  <div class="section1">
  </div>
  <div class="section2">
  </div>
</div>

.section2 {

  float: right;
  padding-right: 100px;
}

.section1,
.section2 {
  box-sizing: border-box;
}

<div class="sections">
  <div class="section1">
  </div>
  <div class="section2">
  </div>
</div>

When faced with scenarios like these, a helpful strategy is to implement this guideline at the start of your CSS code:

* {
  box-sizing: border-box;
}

This directive establishes box-sizing: border-box; for all elements, ensuring that the borders and paddings are factored into the width/height calculations. For example, a container with width: 200px, border: 1px, and padding 10px will truly be 200px wide, including both borders and padding (and not 222px, which would happen without box-sizing: border-box).
