Follow these steps as a beginner in blogging.
Decide a topic.
Write down things you want to talk about in the topic in your understanding and words if possible.
Add examples.
Conclude what you think about the whole topic.
If you find writing a title for an article difficult leave it for last. Have a cover image or if you use Hashnode - use any cover image selected from Unsplash.
If you are just beginning, focus more on writing the contents of the blog and then you can focus on the beautification aspects.
What are the beautification aspects? Use of Markdown headers, quotes, custom images made especially for the blog post, having a custom thumbnail etc.
What things should you take as inspiration from other blogs?
How they lay out the topics - think about it next time you blog, on how can you do the same.
What made that blog look good according to you - replicate in any of your blog posts.
Different topics people selected and think about how can you improve or add to it.
Conclusion: Your first or beginning blogs may look worse, it's okay. Improve by writing on a regular basis. That is how you will improve over time.
