Correction. It should be that = you have before in border color. Get rid of that and replace it with -

So
border-color:

@charlinda18 Youshould add the CSS class in this way :

.thick-green-border{
    border-color: green;
    border-width: 10px;
    border-style: solid;
  }

and also add the class name in the img tag

It should be (-) hyphen not (=)
And create a class thick-green-border to the img element
Check the border-width it should not be 5px
