I have watched the tutorial video and followed it but still the code isn't going

Tell us what’s happening:

Your code so far


<link href="https://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" type="text/css">
<style>
[type='checkbox'] {
     margin: 10px  0px  15px   0px;}
.red-text {
  color: red;
}

h2 {
  font-family: Lobster, monospace;
}

p {
  font-size: 16px;
  font-family: monospace;
}

.thick-green-border {

Challenge: Use Attribute Selectors to Style Elements

Link to the challenge:

If you’re trying to select all input elements with the checkbox type, this might help:

input[type="checkbox"] {
     /* your styling goes here */
} 

{margin: 10px 0px 15px 0px;} is the thing that is preventing me from moving to the next challenge
