How to keep long text elements in the same line via css?

Question

I am not a css/html expert so I'm sorry if I can not explain the problem properly.

I have 2 Wordpress sites with different themes, and I used same widget for them to show the tags. In 1st site, let's name it A, the tags go after another in the same line, even if a tag must be break. In the 2nd site, B, tags go after another too, but in case of all words of a tag can't be at the same line, this tag would go to next line.

UPDATE: What I got in B is like this:

first tag

very large second tag

But in A I got this:

first tag very large

second tag

These tags are different elements, each of which consists of a and span.

This makes white gaps in tag cloud which I don't like. I tried to inspect two themes css via firefox and compare them to identify what to do, but couldn't find the reason. I made any difference in A in B via firefox inspect element but it didn't work.

I put all css codes which firefox gives for the element div#tag-groups-cloud-tabs... in both sites below:

for site A:

inline 139:
*::-moz-selection {
    background: none repeat scroll 0% 0% rgb(73, 138, 184);
}

style.css 137:
*::-moz-selection {
    background: none repeat scroll 0% 0% rgb(73, 138, 184);
    color: rgb(255, 255, 255);
}

inline:
element {
}

style.css 40:
*, html, body, div, dl, dt, dd, ul, ol, li, h1, h2, h3, h4, h5, h6, pre, form, label, fieldset, input, p, blockquote, th, td {
    margin: 0px;
    padding: 0px;
    outline: 0px none;
    vertical-align: baseline;
    background: none repeat scroll 0% 0% transparent;
}

    font: 13px/20px tahoma,'PT Sans',Arial,Helvetica,sans-serif;

and for site B:
