Stuck between flex-end and space-between and margin - html

Question

In a flexbox, when I use justify-content:space-between the first and last items are exactly aligned to the bounds of flex container where space is divided between them. How can I align first item to the right where other items are also aligned to the right (not to entire the width)?
The sample code below is not good because when I use flex-end, I have to set margin for items and so the first one in each row is not sticky to the right.
#flexcontainer{
display: -webkit-flex;
display: flex;
flex-wrap:wrap;
-webkit-flex-direction: row;
flex-direction: row;
-webkit-justify-content: flex-end;
justify-content: flex-end;
background:#ff8800;
}
.flexitem{
display: -webkit-flex;
display: flex;
margin:20px;
width:24%;
background:#666666;
box-sizing:border-box;
height:50px;
}
<div id="flexcontainer">
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
</div>
and this is not also good because items are not aligned to the right (but entire the width):
#flexcontainer{
display: -webkit-flex;
display: flex;
flex-wrap:wrap;
-webkit-flex-direction: row;
flex-direction: row;
-webkit-justify-content: space-between;
justify-content: space-between;
background:#ff8800;
}
.flexitem{
display: -webkit-flex;
display: flex;
margin:0;
width:24%;
background:#888888;
box-sizing:border-box;
height:50px;
}
<div id="flexcontainer">
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
</div>
My desired output in image (first one sticks to the right with no margin-right and the 4th one sticks to the left if 4 element exist and others align to the right if more than 4):

Answer 1

AFAIK the best you can achieve using a flexbox to achieve your desired output can be done manipulating the flex-basis and margin of the flexitems using this:
margin: 20px;
display: flex;
flex: 0 1 calc(25% - 40px);
The flex-basis of calc(25% - 40px) in the flex style divides the width into four adjusting for margin also.
Note I have set flex-grow disabled.
flex-end finishes it up.
Let me know your feedback. Thanks!
#flexcontainer {
display: flex;
flex-wrap: wrap;
flex-direction: row;
justify-content: flex-end;
background: #ff8800;
}
.flexitem {
margin: 20px;
display: flex;
flex: 0 1 calc(25% - 40px);
background: #666666;
box-sizing: border-box;
height: 50px;
}
<div id="flexcontainer">
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
</div>
EDIT:
So I did some more adjustments to the margin calculations:
Change the flex-basis by reducing 10px more to adjust for removing the 20px each at the left and right ends of a row:
flex: 0 1 calc(25% - 30px);
For the rightmost / leftmost boxes to sit to the right / left edge:
.flexitem:nth-child(4n) {
margin-right: 0;
}
.flexitem:nth-child(4n + 1) {
margin-left: 0;
}
.flexitem:last-child {
margin-right: 0;
}
Give me your feedback on this. Thanks!

Answer 2

I guess you could simply remove the right margin in your first example, is this how you wanted it to look?
#flexcontainer {
display: flex;
flex-wrap: wrap;
flex-direction: row;
justify-content: flex-end;
background: #ff8800;
}
.flexitem {
margin: 20px;
margin-right: 0;
width: 24%;
background: #666666;
box-sizing: border-box;
height: 50px;
}
<div id="flexcontainer">
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
<div class="flexitem"></div>
</div>
