Some of my difficulties when designing a blog

When making design a blog, a beginner like myself sometimes have an idea to create a design on my blog, but because I am still learning to make the design so I have not been able to put my ideas on my blog. Along with this article I want to share with my friends all about my ideas and my difficulties in practicing my idea. Through this post might be an inspiration to the reader (who has the same interests as me of course) and more importantly through this post I hope any of my readers who want to share their knowledge and provide guidance to me on my problem.
