"Exploring the world of JavaFX: Unveiling the mysteries

Here are some CSS queries:

How can I create a semi-transparent color using a color variable in CSS?

* {
    -my-color: #123456;
}

.label {
    -fx-text-fill: ???
}

What should be inserted in "???" to achieve a 50% opacity version of -my-color? Is it better to use Java instead of CSS for this task?

How to smoothly transition between colors from default to hover state in CSS?

I aim to switch the color from, let's say, red to blue upon button hover, but I don't want an abrupt change. Would it be more suitable to utilize Java rather than CSS for this purpose?

How do you designate alternative fonts in CSS?

I want to ensure that both Japanese and Arabic text displays correctly using my specified font in TextFields. Unfortunately, I'm facing challenges in achieving this.

EDIT: While I have designated Japanese and Arabic fonts, I need a way for my chosen font to display regardless of the user inputting either language in the TextField.

EDIT2: It is important to note that JavaFX's CSS follows CSS 2.1 standards.

Answer №1

Typically, CSS does not offer that feature. One would need a pre-processor like Less (instructions for JavaFX)


$myColor: #123456;

.label {
    -fx-text-fill: lighten($myColor, 50%)
}

Add
```
transition: color 300ms ease-in-out
```

.my-span {
  color: blue;
  transition: color 300ms ease-in-out;
}

.my-span:hover {
  color: red;
}

<span class="my-span">Hover Me</span>

To list multiple fonts, use commas in this format:

font-family: MainFont, FallbackFont, FallbackFont2, Arial, Sans-Serif

If the browser can't load MainFont, it will try FallbackFont, and so on until falling back to generic Sans-Serif font
