Does it ever matter , Whitespace between HTML elements?

Question

Does it matter ever , Whitespace between HTML elements in source? when we give style through CSS? and need cross browser compatibility

For any browser?

Answer 1

Yes, for example: pretty much any time the data is inline.

Compare:

<p>H<b>e</b>llo, world</p>

and

<p>H <b>e</b> llo, world</p>

Answer 2

Whitespace does matter, but all whitespace is treated as one space. For example,

<span>hello</span> <span>there</span>

Will be rendered by a browser exactly the same as

<span>hello</span>         <span>there</span>

Unless a <pre> tag is being used.

Answer 3

Compare these two lines in a browser:

<img src="..." /> <img src="..." />
<img src="..." /><img src="..." />

You'll see that there is a space between the images in the first line, but not the pair in the second.

Answer 4

Text areas are also affected with whitespace between opening and closing tags as it assumes any content between the two are its content that it should show....
