Milestone style

Hello, I edited the style of my milestones (now they are smaller than they use to) and now there is a large space between my milestones and the link ( especially on the right).

How can I change milestones sizes without having those blank spaces

You can find a snippet showing the problem

Hello Ouassim,
It happens because Gantt has predefined settings for the link position. There is no easy way to change that.
Notice that, by changing the link drag position, you modified it for all projects and regular tasks:

So, even if you adjust the position of the links for milestones, it will affect all other tasks:

And as there is no way to draw links, you need to implement a custom solution.
