Do I have to use for space in Jade?

Question

I am using Jade and everything is cool except that Jade \"eats\" my spaces.

For example, in HTML:

Hello World
<         


        

Answer 1

Of course, when you have two of the same tags after each other, you can simply merge them:

b Hello World

But, if you would have two different sibling tags and would want a space between them, you could use piping to output a space between them.

For example:

b Hello
|     <-- 2 spaces after the pipe
i World

Note that when specifying tag contents / piping text, the actual text content is preceded by a white space. This white space is not outputted. So, in effect, to pipe a white-space you need a | character followed by two spaces.

If you are in an environment where trailing spaces are not preserved, you can alternatively use the following:

b Hello
=" "
i World

= evaluates a JavaScript expression and outputs the result.

Also note that   is not the same as a space in HTML. The correct HTML entity to use is (or if you like hexadecimal numbers).

  stands for non-breaking space. Its character code is 160 ( ). The difference is that where an ordinary space is used, multiple spaces will be shown as a single space and if a line overflows, the text will continue on the next line.* Non-breaking spaces on the other hand will allways be shown. Lines will never wrap where a non-breaking space is used.

This is best illustrated with an example:

 

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    (Note the scroll bar at the bottom.)

_{* This can be overridden with the CSS white-space property. Some elements, such as}

, display all white space and line endings by default.
