CSS: where does this margin come from?

Question

Here's my problem: http://jsfiddle.net/gregseth/548S2/

Why is there a white space between the elements? And how can I get rid of it?

In addition why are the dimensions of the <img> not taken into account on jsfiddle, when it is on a 'normal' HTML page (Firefox)?

Answer 1

This is a result of HTML rendering a space when block items have a space or line break between them. You can either float the items to the left:

or remove the line breaks between the elements:

Answer 2

It's because of the

nav a { display:inline-block; }

If you'd change this to:

nav a {    
    display:block;
    float:left;
}

the margins are gone.

Answer 3

Just apply float:left to the "nav a" in CSS.

Answer 4

It's the spaces (the line breaks) between the <a> elements in your html. This happens on all inline or inline-block elements.

OPTION 1: Use margin-right:-4px; on the <a> tags.

OPTION 2: Remove the spaces between the <a> tags.

OPTION 3: Change the <a> tags to display:block; float:left as described in other answers. In this case, you need to fix the height of the container element (<nav> in your case), or use a clear:left on the next element to prevent the floats overlapping it. Sometimes it's useful to avoid this floating approach and use one of the other options.
