Css properties 25/27


My css code keeps getting error msgs. First the feedback said that I didn't have a border along the image, when switched browsers that went through. Then the error msg says that I set the image height to 201 but it seems to be set at 100. Hoping that I can post my code here. If this happens (I already refreshed and openned a new page, is there a way we can progress to the next lesson anyway?}
enter link description here

h1 {font-family: Verdana, sans-serif; color: #576d94;}
p {font-size: 18px; color: #4a4943; font-family:Garamond, serif;}
img {height: 100 px; width: 300px; border: 1 px solid #4682b4;}
img {border: 1px solid #4682b4;}


there can't be any spaces between 100 and px (it is one "unit"), same with border-property.
