问题 This question already has answers here : In CSS Flexbox, why are there no “justify-items” and “justify-self” properties? (4 answers) Closed last year .

问题 I am working with the CSS grid. I thought that I could make one single grid item to a hyperlink, if I wrapped it in an a tag. But I can see that this solution is not working.
