I need a div filled with colour that goes across the screen behind the bottles like this:
Have tried too many times now...
Here is my html:
.panel {

.OriginalCollection {

}
.inner2 {
height: 100%;
display: flex;
flex-direction: row;
flex-wrap: wrap;
justify-content: center;

margin: 0 auto;
padding: 10px;
}
.centerdivcollections {

Everything is almost done as I want, except this stripe... If you want you can always go to www.konceptxix.com to see the actual site. It's probably an easy fix for someone who knows it well. Sorry for mess in the code, I'm doing my best...
UPDATE:
I can get this set to a position behind it, but it has to be responsive so it's the same on mobile etc...

Answer 1

I'm assuming you want this to go all the way across the page? You'll want to use a pseudo element instead of a div, since it's just a decoration, and you can set the width to something impossibly wide to guarantee it fills the page - you already have overflow set to hidden on the sections, so it won't matter if it gets too wide. I used 150vw and set the left to -50vw, to guarantee that it's always at the far-left of the screen and goes all the way across.
From there, I needed to find a way to target the container for the images, that way I could position the pseudo element consistently as the image gets scaled down without worrying about overlapping the text. So I target the first bottle's first div, which is always the image, that way using different sized images doesn't cause weird double dividers. The result should be what you're looking for!
.bottletextwraper div:first-of-type{
position: relative;
}
.bottletextwraper img{
position: relative;
z-index: 1;
}
.bottletextwraper:first-child div:first-of-type:after{
content: '';
display: block;
width: 150vw;
position: absolute;
bottom: 3%;
left: -50vw;
height: 15%;
background: #662d91;
}

Answer 2

.bottletextwraper {
display: inline-block;
vertical-align: middle;
position: relative;
}
.bottletextwraper::after{
content: '';
position: absolute;
bottom: 0;
left: 0;
right: 0;
height: 100px;
background-color: orange;
}
Try to add this.

Because the stripee is outside of allbottletexwrapper its harder to correctly set the z-indexing. If you can move it inside, you can do without z-index hacks. But anyway, here is what you can do:
//set stripee to be relative and positioned (use your size units)
.stripeee {
position: relative;
top: -190px;
z-index: 1;/*mind this... a bit hacky but... */
}
And then style the bottles:
.bottletextwraper {
z-index: 5; /* use whatever number you consider safe according to the rest of page*/
}
