There are plenty of online tutorials with basic HTML instruction. You can use NotePad or any text editor to create your code and set up a page that would be the default start for your browers. Check your local library and used bookstores if there are any around. Our local Goodwill store has books from time to time. Maybe you have a friend or family member with a HTML book.
Keep your first code attempts very simple: Very basic, no immediate fancy dancing icons, sound effects, and so forth. Just two or three links to sites you deem most useful or important for your needs.
Then expand as warranted.
However, you may not gain as much control as you would like. Once you are on another website they control the ads, pop-ups, etc..
You might take a closer look at the bookmarking options available in your browser. I also use shortcuts on my desktop for key sites; e.g., the Hurricane Center during the storm season. I have a desktop folder that I use to "store" shortcuts that are not used as often. Reduces desktop clutter.
Still it is a good idea so dive in and see what you can do.
Again - keep it simple and do not add something new until everything to date is properly working. Back up your HTML so you always have a good working copy to fall back on. Use revison numbers and dates on the pages you design to keep things orderly. Name the files in the same manner. Keep notes and references. Comment your HTML as well.
And have fun with it.
