I recently bought a domain and have installed WordPress to make a homepage. I'm a Ph.D. student and intend for the homepage to be my online CV; I would like to provide information about my Ph.D.-work, my publications and presentations and similar things related to my professional work. Possibly, I would like to add a blog/a list of articles that I'll be writing, but this should be a subsite of the homepage - i.e. the homepage should not mainly be a blog.
Before starting to add contents, I would like to decide on a theme/template. After a couple of hours of research, I have realized that there are many options, paid and free, and have a couple of questions in that regards:
1) Are themes/templates in general compatible with new versions of WordPress? Are paid themes/template more compatible with updates than free ? Is there a risk that a free theme will stop working when WordPress is updated - or is that unlikely?
2) I have a little bit of experience with HTML, but not a lot. I therefore probably will avoid to write something completely from scratch - but might it be feasible to find a very basic theme/template and then build a design on that? Would there be a risk of non-compatibility of this with updated versions of WordPress?
3) I would like a very simple and minimalistic design of the pages - do you have any recommendations? I know there are plenty of suggested themes out there, but I am particularly interested in suggestions in the view of avoiding non-compatibility discussed above.
Thanks in advance for your reply and suggestions.
