Project portfolio Feedback and suggestions


I have allmost finished the code pen for the portfolio page, but I would like to get some feedback about a few topics.
Here is my pen:

Here is the page on my github.

There is a major difference in the two of them. The code pen doesn’t have working javascript on it. How can I make that happen in the code pen. Further I would like some suggestions about the styling since I am more a backend developer, for this part I really like some feedback.

Try and use padding and margin on elements, rather than br tags.

Thank you for your suggestions. I will take a look into it and change it accordingly.

I updated the portfolio with some new added skills. I think I am missing a background image to fill in the white.
