when writing my code the preview comes up fine if I dont use quotation marks but all the instructions at the side use them.
Are they just something you should always use or is it a flexible thing?

@maxb52,
If you could provide us with the code, you are writing about…
or a link to the course-section…
that would be of help in a eventual explanation.

Of course, sorry I’m quite new to this.
The course section is HTML Basics II 12. Background color
When my code is like this I cannot progress to the next section even though the preview appears correctly.

    <!DOCTYPE html>
<html>
    <head>
        <title>Sexy background color!</title>
    </head>
    <body style=background-color:brown>
        <h3>Favorite Football Teams</h3>
            <ol style=background-color:yellow>
                <li>The Hawthorn Football Club</li>    
                <li>San Franscisco 49ers</li>
                <li>Barcelona FC</li>
            </ol>            
    </body>
</html>

However adding " to the beginning and end of background-colour:brown and background-color:yellowas shown in the examples and as shown here

    <!DOCTYPE html>
<html>
    <head>
        <title>Sexy background color!</title>
    </head>
    <body style="background-color:brown">
        <h3>Favorite Football Teams</h3>
            <ol style="background-color:yellow">
                <li>The Hawthorn Football Club</li>    
                <li>San Franscisco 49ers</li>
                <li>Barcelona FC</li>
            </ol>            
    </body>
</html>

It allows me to progress even though the preview is exactly the same.
I would just like to know if I should always be using " with attributes or is there something else I’m missing?

the quotation marks where mandatory before the arrival of html5. So now it works without quotation marks, but when this course was written it didn’t. I still think without quotation marks it looks weird

Ahhh I see, that makes sense thank you.
I’ve only just started learning HTML yesterday and I have had no experience with code at all before.
Does that explanation also account for

    <p style="background-color: red;">
    Hello
    </p>

and

    <p style="background-color:red">
     Hello
    </p>

(with the first being the way the instructions shows an example) doing the same thing?
Should I learn it the way it was done before HTML5 or does that not matter anymore?

@maxb52,

The style Attribute
has a key:value pair…
if you use more pairs at once,
you will have to use the semi-colon-; as separator
like

 <p style="background-color:red; font-size: 16px">
