Whitespaces

If we want to add something with the different new lines, like multiple lines: Let say:
Line 1
Line 2
Line 3

And we post it as you can see the whitespace and new lines are not preserved and are not being rendered here.

Let's go to recipes and the loop where the content is printed out. And inside <p> tag write style="white-space: pre-wrap". And go back and refresh.

html
{% for recipe in recipes %}
{% if recipe.author %}
<small>Written by {{ recipe.author }} on {{ recipe.date_posted }}</small>
{% else %}
<small>Written by unknown on {{ recipe.date_posted }}</small>
{% endif %}
<h2>{{ recipe.title }}</h2>
<p style="white-space: pre-wrap">{{ recipe.description }}</p>
<a href="/recipes/delete/{{ recipe.id }}" class="btn btn-danger">Delete</a>
<a href="/recipes/edit/{{ recipe.id }}" class="btn btn-primary">Edit</a><br><br>

As you can see, the whitespaces and new lines are all preserved. So, actually, we can have multiple paragraphs per recipe description.

Var alt klart?

Hvordan kan vi forbedre det?
