I need help creating a box with border lines separating different sections. After the H2 heading, I want a new border line followed by a paragraph. However, when I try using border-bottom:1px solid, the line does not reach the edges of the main border. Here is an image for reference: image
Here is my code:
<div class="col-sm-8 col-sm-offset-2" id="house">
<h3 class="text">Our house packages include:</h3>
<ul class="lead text" id="list">
<li>Standard site costs (based on 500mm fall to site & ‘M’ Class slab)</li>
<li>Rainwater Tank or connection to recycled water where available.</li>
<li>Concrete driveway (up to 55sqm)</li>
<li>Tiled Front Porch</li>
<li>Internal Floor Coverings</li>
<li>5+ star gas instantaneous HWS</li>
<li>Wall & Ceiling insulation</li>
<li>‘Classic’ range of inclusions</li>
</ul>
<img src="images/landing.jpg" alt="landing Image">
<p class="note">NB. Please note that all packages are subject to developer and/or council and statutory authorities’ approvals.</p>
</div>
CSS
#house {
border: 1px solid black;
background:white;
}
#house h3 {
border-bottom:1px solid;
font-size:28px;
font-weight:bold;
margin:10px;
}
#list {
font-size:15px;
margin:15px;
padding:15px;
position:relative;
right:20px;
text-align:left;
}
#house img {
width:40%;
position:relative;
left:500px;
bottom:260px;
}
Please help me create border lines after the heading and after the list items as shown in the image provided. It should also be responsive. Thank you!
