Your code needs improvement and does not display correctly in IE. I have cleaned up the HTML and CSS for you to apply the changes needed to fix the issue:
HTML Enhancements Simplify the HTML for that specific section:
<div class="inner-banner">
<div class="left">
<h1> Bring your ideas to life, let's create together. </h1>
<button class="btn btn-custom-am" data-toggle="modal" data-target="#contact_modal"> Contact Me </button>
</div>
<div class="right">
<img src="src/img/banner-design.svg" alt="cube with smoke, smartphone and computer">
</div>
</div>
CSS Adjustments Corrections needed in the CSS:
.banner .inner-banner{
width: 100%;
max-width: 100%;
position: relative;
min-height: 100vh;
}
.banner .inner-banner .left{
width: 40%;
float: left;
position: absolute;
top: 50%;
left: 4%;
transform: translateY(-50%);
-webkit-transform: translateY(-50%);
-moz-transform: translateY(-50%);
color: #ffffff;
}
.banner .inner-banner .right{
width: 70%;
float: right;
position: absolute;
top: 50%;
right: 0;
transform: translateY(-50%);
-webkit-transform: translateY(-50%);
-moz-transform: translateY(-50%);
}
Remove width:450%
from the image as it is unnecessary.
