Survey Form: display problem

Hello, here is the code I am struggling with :

 <fieldset>
           <label>
           What is your favorite feature of freeCodeCamp?
            <select id="feature" name="selection">
              <option value="">Select an option</option>
               <option value="1">Challenges</option>
               <option value="2">Projects</option>

It appears like this, however “What would you like to see improved? (Check all that apply)” is not displayed and the first checkbox is directly next to “select an option”.

I have written in CSS :

label{
  display: block
}

But it does not work.

Could you please help me ?

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

Use closing tag Select.
