This exercize had a hint that said to not forget to add quotation marks around the URL in the src attribute of an img tag. When are quotes and double quotes needed in HTML in general?

How will I know when to use quotation marks in HTML? When should I use it?

I have a question. Please have a look at the above screen shot. Notice the error message, in red letters, on the bottom of the middle panel. It claims that I made a spelling error when it comes to typing the URL in the exercise. I have NOT made a spelling error when it comes to the URL. Now I can’t move to the next exercise.

And yes, I did use a closing >, it’s just that the error message is blocking the >.

You only have part of the URL in the image tag, here’s the full URL


Well formed code always has quote marks around all attribute values. Some attributes are boolean. They are an exception to this rule, only if written implicitly.

 <input type="checkbox" checked="checked">

 <input type="checkbox" checked>

Us old schoolers are pretty set on using double quotes in HTML attributes. I, for one prefer the consistency, even in script generated markup.

 let li = `<li id="item${i}">${item}</li>`

The above is an example of a line in a JS loop.

My course says I haven’t completed my task properly but I don’t know why?

In line 28, the src attribute should be written with quotes around the URL to be well formed.

<img src="%URL">

Of course!

Thank you.

Does the image source address need to be in quotes? My code ran without it.

It’s more a question of convention than what the browser will allow. If we drill down to the core specs, quotes don’t matter in HTML 4. Attributes without quotes are just as valid. However, and that is a big, however, convention suggests that we never write unquoted attributes unless they are booleans.

<input type="radio" checked>

Makes sense! Thank you for the clarification.

Why must we make sure to wrap the link in quotation marks?
