W3C 验证失败，路径段中有非法字符：不允许空格，即使没有空格

Question

Hello I am trying to figure out why is it telling me that the spaces is not allowed even thought from the HTML you can see that there is no spaces in the img

 <img src="media/Review 1.jpg" alt="Review" class="Reviewphoto">

W3C Validation results:

Thanks for your help in advance!

Answer 1

The space is right there, between Review and 1 :

 <img src="media/Review█1.jpg" alt="Review" class="Reviewphoto">
                       ^ here is the space

Do you see it now?

You need to encode it as %20 so the URL becomes media/Review%201.jpg :

 <img src="media/Review%201.jpg" alt="Review" class="Reviewphoto">
