A CSS hack to Visual Studio Code to move the Debug Toolbar

As developers, we’re always looking for ways to enhance our productivity and streamline our workflows. One thing which has bothered me endlessly is the floating Debug Toolbar. I love the fact that it is floating, but I have to move it out of the way every time I want to do something.

Many times I have been thinking to create an extension to move the Debug Toolbar to the titlebar, but I never got around to it. I was thinking about it again today, but unfortunatly, you cannot add CSS for the Visual Studio Code UI without a “hack”.

In this blog post, I’ll share the CSS hack I created to integrate the Debug Toolbar into the titlebar of Visual Studio Code. Follow along as we modify the workbench.desktop.main.css file to achieve this new layout.

Step 1: Create backup copies

Before we modify any files, it’s important to create backups. Open a terminal and run the following commands to copy the original workbench.desktop.main.css file and create a backup:

1
VSCODE_PATH="/Applications/Visual Studio Code.app/Contents/Resources/app/out/vs/workbench"
2
cp -f "$VSCODE_PATH/workbench.desktop.main.css" "./workbench.desktop.main.css"
3
cp -f "$VSCODE_PATH/workbench.desktop.main.css" "./workbench.desktop.main.backup.css"

Step 2: Apply the CSS

Now that we have backups, it’s time to modify the workbench.desktop.main.css file. Run the following command to append the necessary CSS changes:

1
cat << EOF >> "./workbench.desktop.main.css"
2
/* START - DEBUG TOOLBAR */
3
.debug-toolbar {
4
  -webkit-app-region: no-drag !important;
5
  background: transparent !important;
6
  top: 2px !important;
7
  box-shadow: none !important;
8
  border: 0 !important;
9
}
10
"/* END - DEBUG TOOLBAR */"
11
EOF

This CSS snippet modifies the Debug Toolbar’s appearance and positions it within the titlebar. The background property sets the toolbar color, top adjusts the position, and box-shadow and border remove any extraneous styling.

Step 3: Copy the modified file

Finally, we need to copy our modified workbench.desktop.main.css file back to the Visual Studio Code application folder. Run the following command:

1
cp -f "./workbench.desktop.main.css" "$VSCODE_PATH/workbench.desktop.main.css"

Step 4: Restart Visual Studio Code

To see the changes, restart Visual Studio Code. You should now see the Debug Toolbar integrated into the titlebar once you start a debugging session!

You are still able to mode the Debug Toolbar, but you will have to hold the ctrl key + click and drag.
