Example #7 at the end of his article shows a vertically centered block. It does rely on scripting, but it is truly minimal. edit You can also use a single-cell table to accomplish vertical centering.

问题 so I have a div which is min-height 100%; (100% of the screen or more). The child holds the content and needs to be centered vertically, but it might extend the parent to more than 100% of its size. This child is variable in height. So is there a way with only css(3) to do this? 回答1: Use the display: table; and display: table-cell; properties. The outer DIV will need to have display: table; and the inner DIV display: table-cell; along with vertical-align: middle; . Now you will be mimicing

问题 I have a form that is centered according to the screen position that I resize by fontsize when loading. After resizing the location remains the same as it was before resizing so the form is no longer in the center, like I would like. Let me draw you a sketch: I've tried calling this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen; this.ResumeLayout(false); this.PerformLayout(); again after resizing (this is, I believe, the part of the code that centers the form in the
