Blogging Troubles

Although I have previously used blogger I still having a few issues with achieving the layout that I want for a few reasons. I have tried to be proactive about searching online for tutorials and instructions to create certain elements to my blog, although I've learnt quite a lot about coding html and general use of widgets etc that I didn't know before, I have had trouble with then applying them specifically to my blog as some parts couldn't be merged with the theme I have. I have also had problems adjusting some of the structure/layout of the theme (same problem with a few tested themes) for example the images on the initial blog screen are disproportionate and distorted from the original image because they are a preview on the main page. I have tried various suggested methods online and suggestions from IT technicians/tutors but still have not been able to resolve the problem.

Another issue that I have come across is that most tutorials/instruction pages/blogs are made for wordpress even if you search specifically for blogger, apparently this is due to people tagging blogger in their posts purely to attract traffic to the page. This has made it increasingly difficult to find up to date instructions that are actually for blogger. 

This has all been a pretty steep frustrating learning curve because I have not been able to achieve what I want with the look at features of the blog, obviously I will have to keep an open mind about the layout a bit more than I wanted to and HAVE to keep investigating and learning ways to achieve what I want, however I am starting to wonder whether I should try wordpress after all.
