Add space between HTML elements only using CSS

I have several same HTML elements going one after another:

<span>1</span>
<span>2</span>
<span>3</span>

I'm looking for the best way of adding space BETWEEN the elements using CSS only

[no space]  [1]  [space 10px]  [2]  [space 10px]  [3]  [no space]

Additionally:

UPDATE

It looks like I was unclear. I don't want to use ANY ADDITIONAL HTML MARKUP like

<span></span>  <span></span>  <span class="last_span"></span>

I don't want to use tables

I want the first and last span to be targeted automatically by CSS

I don't want to use javascript

Optional requirement: last span can be NOT LAST CHILD of the parent tag, but it will be the LAST SPAN of the parent tag. Spans do not have any other tags between them.

Solution 1:

A good way to do it is this:

span + span {
    margin-left: 10px;
}

Every span preceded by a span (so, every span except the first) will have margin-left: 10px.

Here's a more detailed answer to a similar question: Separators between elements without hacks

Solution 2:

Just use margin or padding.

In your specific case, you could use margin:0 10px only on the 2nd <span>.

UPDATE

Here's a nice CSS3 solution (jsFiddle):

span {
    margin: 0 10px;
}

span:first-of-type {
    margin-left: 0;
}

span:last-of-type {
    margin-right: 0;
}

Advanced element selection using selectors like :nth-child(), :last-child, :first-of-type, etc. is supported since Internet Explorer 9.

Solution 3:

add these rules to the parent container:

display: grid
grid-auto-flow: column
grid-column-gap: 10px

Solution 4:

You can style elements with excluding first one, just in one line of code:

span ~ span {
    padding-left: 10px;
}

No need to change any classes.

Solution 5:

You can take advantage of the fact that span is an inline element

span{
     word-spacing:10px;
}

However, this solution will break if you have more than one word of text in your span
