Vaadin Flow — `Style::set` to specify CSS

Question

我愿从方案上在贾瓦建立一个表格组成部分的边境。我怎么能够这样做,而不必篡改风格?

Answer 1

你可以用一个小组的组成部分总结表格,该小组已经确定了边界。否则,除了使用特别安全局之外,别无选择。

One option, if you wish to stay inside the server environment, is to use the CSSInject add-on and add the border using that (you still need to write CSS, but you can do it on the server in a Java file and not inside a regular CSS file).

Vaadin Flow — `Style::set` to specify CSS

In Vaadin Flow (Vaadin versions 10 and later), you can conveniently set CSS for a widget or layout programmatically. No need to edit separate CSS files, even though styling with CSS files is the recommended way.

On your widget/layout, call getStyle to retrieve the Style object.
On that Style object, call set to pass the name and value of your CSS property.

For example, I find setting a bright colored border on my nested layouts quite helpful for debugging.

myVerticalLayout.getStyle().set( "border" , "6px dotted DarkOrange" ) ;
