CSS - positioning images centrally within a container - html

Question

I'm trying to line up some images within a container and can't seem to move them to make them central. This is how they currently look
I need to sit completely centrally and as is evident they are too far over to the right. I've tried lots of different things but can't get it right. I don't think I'm identifying the correct element.
Here's my code for the section on the photo
body {
margin: 0 auto 0 auto;
}
.container {
margin: auto;
max-width: 100%;
padding-left: 10px;
padding-right: 10px;
}
section#welcome {
height: 500px;
max-width: 100%;
}
section#welcome div.row {
height: 250px;
text-align: center;
position: relative;
}
#welcome h4 {
color: #000000;
font-size: 20px;
padding-top: 50px;
line-height: 5px;
}
section#welcome p {
font-size: 10px;
color: #bdc3c7;
position: absolute;
top: 50%;
left: 50%;
margin-right: -50%;
transform: translate(-50%, -50%)
}
/* centering an image within a column */
section#welcome .four {
position: relative;
display: inline-block;
bottom: 50px;
}
.four h3 {
position: absolute;
color: #FFF;
font-size: 20px;
margin: 0;
top: 50%;
left: 55%;
transform: translate(-50%, -50%);
}
section#welcome img {
display: block;
margin-bottom: 30px;
}
.images,
.four {
margin-right: 100px;
}
<section id="welcome">
<div class="container">
<div class="row">
<div class="twelve columns">

Answer 1

The issue is caused by the margin-right: 100px attribute in the .images, .four class. If you get rid of that, your images should be centered:
.images, .four {
margin-right: 100px; // this line causes your images to offset from center
}
If you still want to have that space in between your images, you can add a margin-left field to balance it out:
.images, .four {
margin-right: 50px;
margin-left: 50px;
}

Answer 2

Use the padding attribute to manually center the images.

Answer 3

This may be help you.
.images { text-align: center; width: 100%; }

Answer 4

Like #yelq said, get rid of the margin-right:100px.
And to make it even more flexible, I would use the display: flex property and use the margin short notation allowing you to change the separation between pictures in only one place.
I would remove the class row from <div class="images row"> since it is not necessary.
In your css, change it to:
.images, .four {
display: flex;
justify-content: center;
flex-wrap: wrap;
margin: 0 50px;
/*margin-right: 100px;*/
}
I would also remove the styling on the img elements and add it to the css, again to allow easier development incase of changes.
.images img {
width:300px;
height:150px;
}
