Styling native elements

Native HTML controls are a challenge to style. You can style any element in the web platform that uses Shadow DOM with a pseudo element ::pseudo-element or the /deep/ path selector.

video::webkit-media-controls-timeline {

}

video /deep/ input[type=range] {

How to mount a VirtualBox shared folder when the Guest OS boots

Problem

While using VirtualBox's Guest Additions to mount shared folders provides a seamless way to mount shared folders, there are also disadvantages.

• Shared folders will always mount in /media/sf_(share name) unless specified using through vbox drivers in the guest OS
• Mounting does not happen at boot-time. Applications that require paths at boot will not be able to access the shared folder even after it is mounted - such as Docker.

Solution

Instead of relying on Guest Additions, if you have sudo permissions, shared folders can be mounted at boot-time using fstab. Using this approach allows
