I recently used CSS to do the layout of a modern website and I was appalled at how things that ought to be simple (such as centering) require hacks & tricks instead of intuitive and legible code. It is unfortunate for a technology so widely used, all the more since CSS had 25 years to improve.
I browsed for alternatives and found that Constraint Layouts (i.e. layout done by specifying equation-like constraints that components have to satisfy) are common in mobile development, but could only find Layx (http://www.layx.org/) for the Web: a promising but incomplete and unmaintained constraint layout engine.

ConstraintLayout provides you the ability to completely design your UI with the drag and drop feature provided by the Android Studio design editor. It helps to improve the UI performance over other layouts. With the help of ConstraintLayout, we can control the group of widgets through a single line of code.
No it it's depends on your need, if you want to make complex layout and want to make them responsive then you can.
ConstraintLayout has flat view hierarchy unlike other layouts, so does a better performance than relative layout. Yes, this is the biggest advantage of Constraint Layout, the only single layout can handle your UI. Where in the Relative layout you needed multiple nested layouts (LinearLayout + RelativeLayout).
To automatically apply any missing constraints you can press the 'Infer Constraints' button at the top of the editor. The red warning sign should now have turned yellow because we have resolved the missing constraints error. Also, the TextView object should have blue arrows coming out of it when selected in the editor.
There is a Constraint Library for react, React Constraint Layout
