Changing part of a style in biblatex

Question

I'm new to biblatex and I want to set up my bibliography. I have searched and found a style that is almost correct.

Is there an easy way to change part of the style in Overleaf?

Below there is a picture of the things I want to change for @Incollection, @Inbook, @Book, and @Article.

Lastly, I have an MWE producing the bibliography and a manual version of how I want it to look.

\documentclass[a4paper,
oneside,
,
12pt]{memoir}

\usepackage[utf8]{inputenc} 
\usepackage[english]{babel} 

\usepackage{csquotes}
\usepackage[
backend=biber,
style=nature,
sorting=none,
maxbibnames=99
]{biblatex}

Answer 1

If there is no pre-made style for what you need, I suggest you start with one of the standard styles (or one of the styles from my biblatex-ext bundle) and not from a customised third-party style. The standard and biblatex-ext styles are intended for customisation, whereas many contributed styles are not.

Some of the easier modifications below are discussed in Guidelines for customizing biblatex styles. Some specifics are from Move names of editors followed by (Ed./Eds.) and a comma before title in biblatex, What's the bibliographstyle of this Bibliography?. The other things should hopefully become clear from the names of the macros involved. Additional hints can be found in the biblatex documentation and the biblatex-ext documentation.

If there are any questions you have about the code that you could not answer with the linked resources, please ask away in the comments.
