In dynamics, using vista-skin, when you hover over a tree element, it has a hover effect where it has a blue background.
In addition, when you click on an element to test it, it has an orange border in chrome and a dotted border in IE.
I try to remove both of them so as not to affect the hover or click once.
See selectMode 3 for an example: wwwendt.de/tech/dynatree/doc/sample-select.html
Update: I found in / src / skin -vista / ui.dynatree.css, if you comment out the following blocks, this will prevent the backlight from blue. In addition, there is a line that needs to be uncommented in order to fix the outline that the web browser fits, as shown below.
background: #F2F7FD; border-color: #B8D6FB; } */ ul.dynatree-container a { outline: 0; }
