JavaFX CSS WARNING: CSS Error parsing file : ... : Expected LBRACE at
提问by Cao Felix
I recently ask a question about adding two vertical lines onto the JavaFX LineChart and now I am having issue with applying some style stuffs to the plots. I think this is a new question so I open a new thread.
我最近问了一个关于在 JavaFX LineChart 上添加两条垂直线的问题，现在我在将一些样式内容应用于绘图时遇到了问题。我认为这是一个新问题，所以我打开了一个新线程。
Add Two Vertical Lines to LineChart
My question: How can I change different color of the series? I also want to change the background to be white.
我的问题：如何更改系列的不同颜色？我也想把背景改成白色。
The following is the chart that I create (it extends LineChart):
以下是我创建的图表（它扩展了 LineChart）：
LineChartWithMarkers<Number, Number> chart = new LineChartWithMarkers<Number, Number>(xAxis, yAxis, dataset);
xAxis.setLabel("time(s)");
yAxis.setLabel("deg/s");
chart.setStyle(".chart-series-line { -fx-stroke-width: 2px; -fx-effect: null; ");
chart.setStyle(".default-color0.chart-series-line { -fx-stroke: blue; }");
chart.setStyle(".default-color1.chart-series-line { -fx-stroke: red; }");
chart.setStyle(".default-color0.chart-line-symbol { -fx-stroke: blue, blue; }");
chart.setStyle(".default-color1.chart-line-symbol { -fx-stroke: red, red; }");
chart.setStyle(".chart-legend { -fx-background-color: transparent; }");
For some reason, those codes won't apply to the chart. So I try to use a CSS file.
出于某种原因，这些代码不适用于图表。所以我尝试使用 CSS 文件。
The following is the CSS file:
以下是CSS文件：
@CHARSET "ISO-8859-1";
.chart-series-line {
-fx-stroke-width: 1px;
-fx-effect: null;}
.default-color0.chart-series-line { -fx-stroke: blue; }
.default-color1.chart-series-line { -fx-stroke: red; }
.default-color0.chart-line-symbol { -fx-background-color: blue, blue; }
.default-color1.chart-line-symbol { -fx-background-color: red, red; }
.chart-legend {
-fx-background-color: transparent;
-fx-font-size: 0.75em;}
.chart-legend-item-symbol{
-fx-background-radius: 2;}
.chart-plot-background {
-fx-background-color: transparent;}
I try to follow Using JavaFX Charts: Styling Charts with CSS, but I get an error in the console is "WARNING: CSS Error parsing file : ... : Expected LBRACE at [1,9]"
我尝试遵循Using JavaFX Charts: Styling Charts with CSS，但我在控制台中收到一个错误是“警告：CSS 错误解析文件：...：预期的 LBRACE 在 [1,9]”
I just switch from JDK 7 to JDK 8 today so I am not sure if it has anything to do with that...
我今天刚从 JDK 7 切换到 JDK 8，所以我不确定它是否与此有关...
Thanks for any help!
谢谢你的帮助！

The @charsetrule is not supported by JavaFX CSS, which is only a subset of full W3C CSS. Try removing it.
该@charset规则不支持JavaFX的CSS，这是唯一的全W3C CSS的一个子集。尝试删除它。
@ Rules
Beginning with JavaFX 8u20, the CSS @import is also partially supported. Only unconditional import is supported. In other words, the media?type qualifier is not supported. Also, the JavaFX CSS parser is non-compliant with regard to where an @import may appear within a stylesheet (see At?rules). Users are cautioned that this will be fixed in a future release. Adherence to the W3C standard is strongly advised.
@规则
从 JavaFX 8u20 开始，还部分支持 CSS @import。仅支持无条件导入。换句话说，不支持 media?type 限定符。此外，JavaFX CSS 解析器不符合 @import 可能出现在样式表中的位置（请参阅 At?rules）。提醒用户，这将在未来版本中修复。强烈建议遵守 W3C 标准。
