Filling Extra Space in HTML/CSS - html

Question

How do I fill that circled space? I want to know how to fill the rest of the blue area with white background-color.
I tried increasing the padding, but that moved the price lower and lower and to the left a little each time I increased the padding.
My HTML looks like this..
section {
background-color: white;
}
#repair-tagline h1 {
background-color: white;
font-family: 'Open Sans Condensed', sans-serif;
letter-spacing: 0.2rem;
font-size: 3rem;
text-align: center;
padding: 40px 0 40px 0;
}
.repair-option {
background-color: rgb(0, 0, 77);
width: 80%;
padding: 50px 50px 50px 50px;
margin: 0px auto 50px auto;
}
.repair-type,
.repair-price {
display: inline-block;
color: white;
}
.repair-type {
font-size: 2rem;
}
.repair-price {
float: right;
background-color: white;
border: 1px solid black;
color: black;
font-size: 2rem;
}
<section>
<div class="repair">
<div id="repair-tagline">
<h1>Choose Your Vacuum Cleaner Repair Option:</h1>
</div>
<div class="repair-option">
<div class="repair-type">
<h1>Belt Repair</h1>
</div>
<div class="repair-price">
<h1>$10.00</h1>
</div>
</div>
<div class="repair-option">
<div class="repair-type">
<h1>Brush-Roll Repair</h1>
</div>
<div class="repair-price">
<h1>$20.00</h1>
</div>
</div>
</div>
</section>

Answer 1

Remove the padding from the class of repair-option and add individual paddings to the 2 child divs (repair-type and repair-price). That way, each of those had individual paddings which means the background-color corresponds to the div.
The padding for .repair-price may look weird, but I just did that because it wasn't lining up. You can change all the paddings to how you wish.
section {
background-color: white;
}
#repair-tagline h1 {
background-color: white;
font-family: 'Open Sans Condensed', sans-serif;
letter-spacing: 0.2rem;
font-size: 3rem;
text-align: center;
padding: 40px 0 40px 0;
}
.repair-option {
background-color: rgb(0, 0, 77);
width: 80%;
padding: 0px;
margin: 0px auto 50px auto;
}
.repair-type,
.repair-price {
display: inline-block;
color: white;
}
.repair-type {
font-size: 2rem;
padding: 10px;
}
.repair-price {
float: right;
background-color: white;
border: 1px solid black;
color: black;
font-size: 2rem;
padding: 10px 0px 8px 0px;
}
