Set inline-svg as the background of a div - html

Question

I got a place on my CSS Grid where I am inserting a paragraph of about 15 characters long, I would like to add a background element to it and I want it to have some personality so am using a inline SVG content.
I tried to place it at the bottom with a position:relative but when you change the view-port size it doesn't scale well. I wrapped the SVG code in a container:
.marquee-container {
height: 0;
position: absolute;
width: 500px;
}
And the styles of the SVG:
.svg-marquee {
fill: teal;
stroke-width: 4;
stroke-miterlimit: 10;
cursor: pointer;
transition: .5s;
}
This is the HTML Markup
<div class="home-works">
<div class="head">
<h1>Entries</h1>
</div>
<img class="thumbnail" src="img/profile-picture.png" width="100%"/>
<div class="main-content">
<div class="marquee-container">
<svg version="1.1"
xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:a="http://ns.adobe.com/AdobeSVGViewerExtensions/3.0/"
x="0px" y="0px" viewBox="0 0 634 175" style="enable-background:new 0 0 634 175;"
xml:space="preserve">
<path class="svg-marquee" d="M595.9,173C317,173,317,153,38.1,153C27.3,153,2,157.6,2,151C2,87.5,34.8,87.5,34.8,24c0-6.6-7.5-22,3.3-22
C317,2,317,22,595.9,22c10.8,0,36.1-4.6,36.1,2c0,63.5-32.8,63.5-32.8,127C599.2,157.6,606.7,173,595.9,173z"/>
</svg>
</div>
<div class="post">
<h3>title</h3>
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Tempore placeat
maiores ad ullam illo, blanditiis ipsam libero! Aspernatur, mollitia suscipit?
</p>
</div>
</div>
</div>
My item is inside a CSS Grid Layout where post is the class I am using to style the contents of the paragraph. Which is not inside any grid-template-areas, its just a class within an area already defined.
.post {
text-align: left;
position: relative;
z-index: 1;
}
So the scaling doesn't go well, I would like to place the element at the background of the paragraph to be contained, what is the best approach?
.marquee-container {
height: 0;
position: absolute;
width: 500px;
}
.svg-marquee {
fill: teal;
stroke-width: 4;
stroke-miterlimit: 10;
cursor: pointer;
transition: .5s;
}
.post {
text-align: left;
position: relative;
z-index: 1;
}
<div class="home-works">
<div class="head">
<h1>Entries</h1>
</div>
<img class="thumbnail" src="img/profile-picture.png" width="100%" />
<div class="main-content">
<div class="marquee-container">

Answer 1

Since you are positioning the .marquee-container absolutely.
You need a parent to have position set to relative, So, add position: relative on the parent .main-content.
I don't understand why you set the .marquee-container height to 0.
I would suggest set it's height to auto and have a bottom: 0;, (As you wanted it to be aligned to bottom of the container).
Set the width to 100% since you want it to be scalable. also add a negative z-index so that the element doesn't cover up the contents.
Check the snippet below.
.main-content {
position: relative;
}
.marquee-container {
position: absolute;
bottom: 0;
height: auto;
width: 100%;
z-index: -5;
}
.svg-marquee {
fill: teal;
stroke-width: 4;
stroke-miterlimit: 10;
cursor: pointer;
transition: .5s;
}
.post {
text-align: left;
position: relative;
z-index: 1;
}
<div class="home-works">
<div class="head">
<h1>Entries</h1>
</div>
<img class="thumbnail" src="img/profile-picture.png" width="100%" />
<div class="main-content">
<div class="marquee-container">
