Base code update!

Instructions + code

After about 3 years, I revisited my base code and decided it needed to be completely overhauled.

This theme is fully functional on its own, but you can use it to make your own themes! I wanted to include blocks and variables that I don't usually see in base codes (like highlighted posts and day pages) without making it too overwhelming. You can view the preview blog @eggbasecode to see how it looks without editing.

Unlike the previous versions, I wrote an in depth guide to go this base code. This includes a general overview of how HTML and CSS are used in themes and explanations on what the blocks and variables are doing.

Whooboi, there is a lot of discourse going on right now about JCINK coders. Perfect time for me to update some base skins!

For those who just want to streamline their coding process, I have updated my widowbase v3 to include a day/night theme toggle and made a few responsive tweaks to the vertical nav and sidebar. For those looking to learn how to use CSS grid and flexbox to create responsive forum designs, I added a new base, widowbase v4. This version includes some HTML templates that have a very ugly, extremely basic, but functional fluid grid layout. These templates also incorporate hidden divs (read as, display: none) that include the PHP variables frequently used inside those respective HTML templates, so you can easily delete everything I've done and start from scratch with your own. Then just delete the hidden div when you've used everything you need. Easy peasy!

I haven’t seen any page base codes recently so I decided to make these. There are no scripts in any of these so they can be used without requesting a javascript exception from tumblr. There is little/no styling here since it’s meant to be a starter for your own design. Since these are all bases, the credit can be removed/changed if you make it into your own page.

Theme07: Base Code

A base code with a very minimal design for those who wants to start their theme-making journey. 

This theme is also suitable to be used as it is. I’ve made a very minimal design for this theme to cater the users who are looking for a minimal design with good readability (if you want to add a background, you need to manually add it inside the code thou).
