If you set a style for a pre or div once, do you need to set again?

for example, if i do: 

pre style="white-space:pre-wrap;"

at the beginning of my first pre block, would this apply to all pre blocks? it doesn't seem to have the effect I want.

Solution

  • No, if you define your style directly inside your <pre> tag, it will only be applied to this element.

    Define your CSS properties in a <style> block, and it will be applied to all <pre> elements:

    <style>
pre {
    white-space: pre-wrap;
}
</style>

    Simply place this block inside the <head> of your HTML document.
