Using CSS to Draw 3 Vertical Lines on an Image - html

Question

So I'm really new using CSS, I need to add 3 vertical red lines on top of an image, the lines have to split the image in 4 equally sized parts. The size of the image is always 465*346 and the mark up I have so far looks like this
CSS:
.logo-container {
position: relative;
height: 87px;
width: 35%;
margin: 0 auto;
min-width: 144px;
}
.logo {
position: relative;
width: 72px;
height: 87px;
z-index: 2;
}
.logo-line {
position: relative;
display: inline-block;
top: -50%;
width: 20%;
height: 2px;
background: #333;
}
HTML:
<div id="preview-image-wrapper">
<span class="firstOverlayLine" ></span>
<span class="secondOverlayLine"></span>
<span class="thirdOverlayLine"></span>
<img id="mainImage" type="image" class="mainimage" data-bind="attr: {src: SelectedImagePath}" />
</div>
The above is my attempt to modify this example to make it fit my needs, but with no success so far.
The end result should look like:

Answer 1

You can do something raw like this - floating 1px-wide spans over the image, keeping your original HTML:
div {
width: 465px;
position: relative;
}
span {
position: absolute;
display: block;
height: 346px;
width: 1px;
background: red;
}
.firstOverlayLine {
left: 25%;
}
.secondOverlayLine {
left: 50%;
}
.thirdOverlayLine {
left: 75%;
}
<div id="preview-image-wrapper">
<span class="firstOverlayLine"></span>
<span class="secondOverlayLine"></span>
<span class="thirdOverlayLine"></span>
<img src="http://placehold.it/465x346">
</div>

Answer 2

You could use :before and :after :pseudo-elements.
#img {
position: relative;
width: 465px;
height: 346px;
background: url(http://dummyimage.com/465x346/ddd5ed/fff);
border: 1px solid red;
}
#img:before, #img:after {
position: absolute;
content: '';
width: 25%;
height: 100%;
top: 0;
left: 25%;
border-left: 1px solid black;
border-right: 1px solid black;
box-sizing: border-box;
}
#img:after {
left: 75%;
border-right: 0;
}
<div id="img"></div>

Answer 3

Alternative using unordered list:

<div id="preview-image-wrapper">
<ul>
<li></li>
<li></li>
<li></li>
</ul>
<img src="http://placehold.it/465x346" />
</div>
div, img {
width: 465px;
height: 346px;
position: relative;
}
ul {
margin:0;
padding:0;
list-style-type: none;
position: absolute;
display: block;
height: 346px;
width:100%;
z-index:200;
overflow:hidden;
}
li {
height:346px;
border-right:1px solid red;
width:25%;
display:inline-block;
margin-right: -4px;
}

Answer 4

For a horizontal line, if someone needs it.
div {
width: 465px;
position: relative;
}
span {
position: absolute;
display: block;
height: 2px;
width: 465px;
background: red;
}
.firstOverlayLine {
top: 50%;
}
<div id="preview-image-wrapper">
<span class="firstOverlayLine"></span>
<img src="http://placehold.it/465x346">
</div>
