JuNe / JUst NEeded Philosophy
- Source code using less code as possible So you can understand code and find bugs easier.
- Few and optimized lines is better Elegant design.
- Avoid external dependencies abuse/bloated, and possible third-party bugs Less files size, better and faster to the interpreter.
- Clear and useful documentation with examples and without verbose Get to the point.
- Avoid showing unsolicited popups, notifications or messages in frontend For better User eXperience.
- Simple UI, without many menus/options and with few clicks to get to sites.
- Consequences of having a lot of code (and for simple things): Having to work and search through many files and folders with a lot of wasted time, successive errors due to missing unknown files, madness to move a code to another project, errors due to recursive dependencies difficult to locate, complexity or impossibility to migrate to new versions, unfeasibility to follow the trace with so much code, risk of new errors if the functionality is extended, problems not seen at the first sight, general slowness in the whole development due to excessive and unnecessary code.
Prefixed custom properties / variables with --jc (JuNe CSS). You can change your corporative (dark) color jcbtheme, and your custom font.
- Light: means a bright color.
- Dark: means a darker color.
- Combination of foreground/background with light/dark or dark/light must be readable/legible.

- jcclr + jcbg: are used to main color and backgrounds (light).
- jcclight + jcbglight: are used as reversed main color and backgrounds (dark) for headers/footers.
- jcbbclr + (jcbtheme, jcbblue, jcbgreen...): are used for buttons and backgrounds (dark).
Main color and background are reversed, and the (visuality) meaning changes: light is dark and dark is light.

There is no problem in using inline styles. It is not a bad practice even if you read wrong about it. In many occasions it´s the best option for small styles. That way they are located in their HTMLElement, and so the style file does not grow, nor is it necessary to create a class for individual single-use styles. It also improves the visualization since the style is applied instantly without having to wait for the CSS to load. Really the bad practice is to create a large and unoptimized style file, with unused classes, that is difficult to manage, hard to find anything and takes longer to load.
For best image/iframe loading performance when it´s possible to show in a visible window area, add loading tag <img src="..." loading="lazy">
In most cases you may only need to change the theme color, so just add it after the CSS:
<style>
:root {
--jcbtheme: #FEA700;
}
</style>
Or using JS on window load:
document.documentElement.style.setProperty('--jcbtheme', '#FEA700');
Do not use small styles and keep in mind that presbyopia begins at age 40, that is 26% of world´s population (1.8 billion) and more than 80% in adults. 👥Think of everyone. JuNe CSS is designed for presbyopia people, avoiding small designs and using high contrast. Also spacing of elements for easy clicking on touch devices and to facilitate people with disabilities.
- Choose the CSS file you need and fonts files required (and create
fonts/folder in your project). - Add to your HTML head project with
<link rel="stylesheet" href="/june-css.min.css" /> - Remember to change
fonts/path if you prefer another location (recommended absolute paths / ). - Change your corporative/main color in
jcbtheme(default orange #fea700). - Change
sansseriffont if you prefer other font and adjust--jcfntname, and@font-face family / srcpath. - Only woff2 (Web Open Font Format) is needed by browsers nowadays. TTF (or OTF) to WOFF2 converters: cloudconvert, Everything Fonts or fontConverter.
- Keep in mind to choose a font that includes accents or characters for other languages.
