Responsive Image and Text side by side - html

Question

I'm trying to make 2 columns:
The first is an image taking 50% of the page and the other would be a text box taking the remaining 50% of the page. No margins.
Is it possible to have something like this that's responsive? I'm struggling to get the background colour to line up with the image.
.imagebox {
width: 50%;
float: left;
}
.textbox {
width: 50%;
float: right;
text-align: center;
padding-top: 20px;
background-color: #666;
color: #fff;
}
<div class="imagebox">
<img src="http://www.mokshasoulyoga.com/wp-content/uploads/2017/04/5.png" width="100%" height="auto" />
</div>
<div class="textbox">
<h2>Title Here</h2>

Answer 1

Here the first half is an <img> and the second is a <textbox>
https://jsfiddle.net/b8ow0noy/1/
The code from the link is here
<div style="width: 50%; float:left">
<img src="https://www.w3schools.com/css/trolltunga.jpg">
</div>
<div style="width: 50%; float:right">
<textbox>
#right content in there<br>
#right content in there<br>
#right content in there<br>
#right content in there<br>
#right content in there<br>
#right content in there<br>
#right content in there<br>
#right content in there<br>
#right content in there<br>
#right content in there<br>
</textbox>
</div>
css:
div{
margins:0 px;
overflow:hidden;
}

Wrap your .textbox inside a container (in my case the class of the container is .textbox-cont). Give imagebox and textbox-cont a fixed height. Remove floating property from textbox apply it to the .textbox-cont. Now position both the image and the textbox relative to the .imagebox and .textbox-cont respectively.
Use position absolute for img and .textbox and position it 50% from the top of their container like so:
.imagebox img{
position:absolute;
top:50%;
transform:translateY(-50%);
}
.textbox{
background-color: #666;
color: #fff;
position:absolute;
text-align: center;
width:100%;
top:50%;
transform:translateY(-50%);
}
This will do the trick. Also if you want to make it responsive use media queries like so:
#media only screen and (max-width: 700px) {
.imagebox,
.textbox-cont{
width:100%;
height:200px;
}
}
Play around with the breakpoint (max-width) and change it to whatever suits you best.
Also change the box-sizing property of every element to border-box like so to fix any margin or padding issue:
*{
box-sizing:border-box;
}
Final snippet :
*{
box-sizing:border-box;
}
.imagebox {
width: 50%;
float: left;
height:300px;
position:relative;
}
.imagebox img{
position:absolute;
top:50%;
transform:translateY(-50%);
overflow:hidden;
}
.textbox-cont {
width: 50%;
height:300px;
float: right;
position:relative;
overflow:hidden;
}
.textbox{
background-color: #666;
color: #fff;
position:absolute;
text-align: center;
width:100%;
padding:20px;
top:50%;
transform:translateY(-50%);
}
#media only screen and (max-width: 700px) {
.imagebox,
.textbox-cont{
width:100%;
height:200px;
}
}
<div class="imagebox">
<img src="http://www.mokshasoulyoga.com/wp-content/uploads/2017/04/5.png" width="100%" height="auto" />
</div>
<div class="textbox-cont">
<div class="textbox">

The following answer is responsive but at small widths the image will be very narrow and probably cropped too much. At a certain breakpoint you might want to convert the side-by-side layout to a stacked single column.
.wrap {
display: flex;
}
.wrap>* {
flex: 1;
}
.imagebox {
position: relative;
}
img {
width: 100%;
height: 100%;
object-fit: cover;
}
.textbox {
padding: 1rem;
background-color: #666;
color: #fff;
}
<div class="wrap">
<div class="imagebox">
<img src="http://www.mokshasoulyoga.com/wp-content/uploads/2017/04/5.png" width="100%" height="auto" />
</div>
<div class="textbox">
<h2>Title Here</h2>
