[{"content":"There are many ways you can make advanced changes to Blowfish. Read below to learn more about what can be customised and the best way of achieving your desired result.\nIf you need further advice, post your questions on GitHub Discussions.\nHugo project structure # Before leaping into it, first a quick note about Hugo project structure and best practices for managing your content and theme customisations.\nIn summary: Never directly edit the theme files. Only make customisations in your Hugo project\u0026rsquo;s sub-directories, not in the themes directory itself. Blowfish is built to take advantage of all the standard Hugo practices. It is designed to allow all aspects of the theme to be customised and overriden without changing any of the core theme files. This allows for a seamless upgrade experience while giving you total control over the look and feel of your website.\nIn order to achieve this, you should never manually adjust any of the theme files directly. Whether you install using Hugo modules, as a git submodule or manually include the theme in your themes/ directory, you should always leave these files intact.\nThe correct way to adjust any theme behaviour is by overriding files using Hugo\u0026rsquo;s powerful file lookup order. In summary, the lookup order ensures any files you include in your project directory will automatically take precedence over any theme files.\nFor example, if you wanted to override the main article template in Blowfish, you can simply create your own layouts/_default/single.html file and place it in the root of your project. This file will then override the single.html from the theme without ever changing the theme itself. This works for any theme files - HTML templates, partials, shortcodes, config files, data, assets, etc.\nAs long as you follow this simple practice, you will always be able to update the theme (or test different theme versions) without worrying that you will lose any of your custom changes.\nChange image optimization settings # Hugo has various builtin methods to resize, crop and optimize images.\nAs an example - in layouts/partials/article-link/card.html, you have the following code:\nThe default behavior of Hugo here is to resize the image to 600px keeping the ratio.\nIt is worth noting here that default image configurations such as anchor point can also be set in your site configuration as well as in the template itself.\nSee the Hugo docs on image processing for more info.\nColour schemes # In addition to the default schemes, you can also create your own and re-style the entire website to your liking. Schemes are created by by placing a \u0026lt;scheme-name\u0026gt;.css file in the assets/css/schemes/ folder. Once the file is created, simply refer to it by name in the theme configuration.\nNote: generating these files manually can be hard, I\u0026rsquo;ve built a nodejs terminal tool to help with that, Fugu. In a nutshell, you pass the main three hex values of your color pallette and the program will output a css file that can be imported directly into Blowfish. Blowfish defines a three-colour palette that is used throughout the theme. The three colours are defined as neutral, primary and secondary variants, each containing ten shades of colour.\nDue to the way Tailwind CSS 3.0 calculates colour values with opacity, the colours specified in the scheme need to conform to a particular format by providing the red, green and blue colour values.\n:root { --color-primary-500: 139, 92, 246; } This example defines a CSS variable for the primary-500 colour with a red value of 139, green value of 92 and blue value of 246.\nUse one of the existing theme stylesheets as a template. You are free to define your own colours, but for some inspiration, check out the official Tailwind colour palette reference.\nOverriding the stylesheet # Sometimes you need to add a custom style to style your own HTML elements. Blowfish provides for this scenario by allowing you to override the default styles in your own CSS stylesheet. Simply create a custom.css file in your projec
