I have a question related to HTML. In order to demonstrate my simple question, I will use a minimal example.
Consider the following HTML content:
<html>
Foo: Bar
</html>
When you call this in a browser, it displays "Foo: Bar" in one line. So far so good.
However had, when you do almost the same, and store this:
<html>
Foo
: Bar
</html>
In other words, if you add a newline right before the ':' character, then suddenly the display becomes this here:
"Foo : Bar"
Now I wonder where from the ' ' comes? Because that character is not part of the original source.
In HTML a carriage return or line feed in the source code is treated as white space and rendered as a space. Multiple spaces or white space (CR, LF, tabs, etc.) amount to a single white space on the rendered page.
So if you have 50 carriage returns in your source code between
Fooand: Barit will render a one space (Foo : Bar) when th HTML page is displayed in the browser.From the HTML 4.01 spec: Controlling line breaks.
