Without going further to make the page responsive I stopped eveything to focus on getting the layout right in the first place. As per the tutorial there are certain items that need to be working as the following plan and there are things I can not figure out:
1) The aside tags (there are 3 of them: top-sidebar, middle-sidebar and bottom-sidebar ) need to be going to the right of the articles and arrange from top to bottom.
2) The links in the nav need to be arranged with inline-block(so they are side by side) and also display an orange colour. The behaviour of the “nav ul” and “nav ul li” seems to be still in default mode.
The finished page image including html, css and logo files are downloadable from this link:
