By default we've kept the landing page's stylesheet separated from the blog to improve the overall performance but if you'd like to use the landing page's modules on the blog listing or post page, simply attach the landing page's stylesheet with the main theme.
Go to Design tools and find the Awwal blog theme.
Now go to Templates folder > Layouts folder > base.html
Paste the following code right below the main.css line. See the screenshot for more clarity.
