As a programmer, I recommend that you write a blog website yourself instead of using blogger.
A few days ago, I used Blogger and I found its editor very difficult to use. Because I am a programmer, I need to paste the code, but the display of the code in Blogger is very bad. For example, the style I thought would work, but it didn't work on Blogger. I think the CSS style has been overwritten. So I opened the source code and read it. The source code is too long and messy that I don't want to change it.
Blogger is great for beginner, but not for me. Probably the biggest benefit of Blogger is that it is free.
My editor is CKEditor, which has been modified by me and is now very suitable for my use, whether it is writing code or mathematical formulas. But I found that if I want to achieve the same effect on Blogger, it is more difficult than flying. I think I must modify the underlying code, and it will take me a lot of time.
Some people say that there is a way to use markdown on blogger. But I think this is too troublesome, it is time-consuming and unstable. And markdown itself is not a particularly good solution. If you are just a blog site, you only need to develop it yourself, with the least amount of code.
Believe me, when you have used CKEditor, you probably don't want to use other editors.
