# Learn Accessibility by Building a Quiz - Step 9

Can someone explain what is meant by the aspect-ratio of 35/4. What does the top number mean and what does the bottom number mean when they refer to svg’s? I clicked on the freeCodeCamp styleguide but it doesn’t tell me much about it or I just can’t find it…

Padding has a value of “0.4rem” and add a blank space in front of number “4” in the ‘aspect-ratio’ property:

``````padding: 0.4rem;
``````

its missing an expected value, lets read from instructions to see what that value is

. Finally, add a `padding` of `0.4rem` all around

happy learning

Ok, but what has the missing padding to do with my question?
