Angular add blog feature component using HTML blog template

We've an ecommerce angular fully built project and we've purchase a new HTML out of box blog template (with all CSS and JS etc).

We need to create a blog component in our angular project and bring this ready-made HTML blog to make it dynamic.

Current state: We've created a component and added all relevant files. It renders perfectly within our page. But the CSS or JS is not functioning as expected.

Task Required:
1. Fix CSS and JS. Also, we'll need to make the content (blogs) appear dynamically (API) on blog home. And single blog page. API's are provided by our backend team.

2. Implement pagination.

3. Render components data from our API.

See attached screenshots of original template and our angular project (imported template with css/js).
