JavaFX how to remove the borders from button

https://i.stack.imgur.com/Y76Fl.png
On this picture on left side - running java program, and right side - Scene builder layout.
This is my github code: https://github.com/captsmile/calc

You can do the following code in .css file
.button
{
-fx-background-color: transparent;
}
This will make the color of button as the color of your application's background color(due to transparency).
Furthermore you may also apply some effects to make your button looks more cool. To add effects
.button:hover
{
-fx-background-color: yellow;
}
.button:pressed
{
-fx-background-color: brown;
}
At the end ,you may attach the case file with your file(suppose index.java file in which you want to apply css) by writing following code in your index.java
scene.getStylesheets().add(getClass().getClassLoader().getResource("application.css").toExternalForm());
Where application.css is the css file with whole css code given above . This application file must be present in your src folder.

I fixed this removing border at GridPane
.root{
-fx-padding: 5;
-fx-border-style: none;
-fx-border-width: 0;
-fx-border-insets: 0;
}

This is how you can do it in scenebuilder
Choose the button by clicking on it.
Then in properties->Style
Choose "-fx-background-color"
and put value as " transparent"
Like this

You can do it by JavaFX CSS selectors on the button.

Style Layout Panes in CSS with JavaFX FXML without creating a variable?

I'm working with JavaFX FXML, and I'm having a bit of trouble styling my app with CSS.
I have a GridPane on my root node, and I'd like to style it's background. The GridPane itself was never mentioned in the Java code (#FXML) because it didn't have to - it was never used at all in the code.
However, I'm styling the app now and all I can get from Oracle's Official Guide of Styling Layout Panes with CSS is that I'll have to create a variable like so: GridPane grid = new GridPane(); and then proceed to assign the variable a style, like so:
.grid {
-fx-background-color: white;
-fx-background-radius: 5.0;
-fx-background-insets: 0.0 5.0 0.0 5.0;
-fx-padding: 10;
-fx-hgap: 10;
-fx-vgap: 10;
}
And then proceed to add the style to it, like so: grid.getStyleClass().add("grid");.
This is an unfeasible solution for me as I have multiple GridPanes in multiple scenes throughout the project, and I can't have to manually create a variable for all of them.
Is there a solution similar to styling a button?
A button can be styled without requiring to create a variable for it, and it will automatically style all buttons on the scene, like so:
.button{
-fx-text-fill: rgb(49, 89, 23);
-fx-border-color: rgb(49, 89, 23);
-fx-border-radius: 5;
-fx-padding: 3 6 6 6;
}

GridPane doesn't have a own style class (see CSS reference), but similarly to tag selectors in HTML, Nodes can be selected by their java classes:
GridPane {
-fx-background-color: white;
-fx-background-radius: 5.0;
-fx-background-insets: 0.0 5.0 0.0 5.0;
-fx-padding: 10;
-fx-hgap: 10;
-fx-vgap: 10;
}
Furthermore is is possible to add style classes from FXML since styleClass is a Read-Only List Property:
Short form for a single style class:
<GridPane styleClass="grid">
...
Long form for multiple style classes:
<GridPane>
<styleClass>
<String fx:value="grid"/>
<String fx:value="myclass"/>
</styleClass>
...
It is also possible to add style classes from the properties view in SceneBuilder.

JavaFX CSS styling of TextArea does not work

I'm writing a simple JavaFX application, but I can't get some of the CSS styling to work.
The problem is the -fx-background-color property for my TextArea.
This is the relevant CSS:
.text-area {
-fx-font-family: Consolas;
-fx-highlight-fill: #00ff00;
-fx-highlight-text-fill: #000000;
-fx-text-fill: #00ff00;
-fx-background-color: #000000;
}
All the fields perform as expected, except -fx-background-color, which apparently does nothing. I still have the default white background. As you can see in the picture, the TextField below, which has identical CSS, but does apply the background color as expected.
Picture of my problem
Any clues?

You need to set the content:
.text-area .content{
-fx-background-color: black;
}
...
Or see this answer maybe: Transparent background of a textarea in JavaFX 8

I had the same problem: What I did:
Created a .css file called console.css with following content:
.text-area {
-fx-font-family: Consolas;
-fx-font-size: 15;
-fx-text-fill: #ffffff;
-fx-display-caret:true;
}
.text-area .content {
-fx-background-color: #000000;
}
On my scene called:
scene.getStylesheets().add(this.getClass()
.getResource("/stylesheets/console.css").toExternalForm());
Explanation:
The second part just loads the css stuff. (trivial)
The fist part (css): You have to check which property has to be applied on which part of the object. For instance: -fx-font-family is on .text-area but -fx-background-color is on .content. Understanding this concept let you understand all of the css stuff in JavaFx.

Good programming :-)

Are you using scene builder?
I tried the same css you use and everything works fine, maybe it's a bug in your version.
I tested it for text-area and text-field.

You should use -fx-control-inner-background for example for a TextArea with id=textAreaField:
#textAreaField {
-fx-control-inner-background: #000000;
-fx-text-fill: #ffffff;}
and you can for more information, see this topic:
Textarea javaFx Color

In JavaFx ,TextArea has two substuctures (Content & scrollPane) ,for each structure has all properties of TextInputControl :
text-area{ }
text-area .content { }
text-area.scroll-pane { }

css img:hover working, img:active is not

I have the following code, which displays the images in my table with no border, then an orange border when hovered over:
table.test {
}
.test img {
border: solid 4px transparent;
}
.test img:hover {
border-color: orange;
}
If it try the following, i expect the border to stay orange after click, but it does not
.test img:active {
border-color: orange;
}
The images being used are thumbnail size instead of checkboxes.
Any ideas how I can keep the border orange after click?

Images cannot use active. http://www.whatwg.org/specs/web-apps/current-work/multipage/selectors.html#selector-active.Wrap it within an anchor and prevent default on the anchor click and change the cursor maybe?

check this fiddle might help you using simple jquery let you give your output
$('.test img').on('click', function(){
//use jquery css function
$(this).css({"border-color":"orange"});
// or add class .active with your own style
$(this).addClass('active');
})
make your image as block element and add this jquery click event. solved

You can create a class called orangeborder (or anything, really). Give it the attributes of border-color:orange;.
Then you can use jQuery and use:
$('img').click(function(){
$(this).toggleClass('orangeborder');
});

javafx 2.0 adding border to Label

I have a label with style class "test" in my javafx application.
I wanted to add white border around this label, so in the css file I tried:
-fx-border-width: 2;
-fx-border-color: white;
but that didnt worked so then i tried to add:
-fx-border-style: solid;
but that didnt worked either, following javafx css reference I didn't find anything useful.
what am I doing wrong?

Can you try:
System.out.println(label);
it should print something like
Label#1858c80c[styleClass=label]
Is your css class printing too after styleClass=label ... ?
Or can you remove css class of the label and try setting the label style in code directly by:
label.setStyle("-fx-border-color: white;");
if you can see the changes then maybe you are unintentionally overriding css class definiton in css file. Check it.
