          What is CSS Flexbox?

          CSS Flexbox (Flexible Box Layout) is a one-dimensional layout model that lets you distribute space and align items in a container, even when their sizes are unknown or dynamic. It makes complex layouts straightforward without floats or positioning hacks.

          What does justify-content do in Flexbox?
          ▼
        
        

          justify-content aligns flex items along the main axis (horizontally when flex-direction is row). Options include flex-start, flex-end, center, space-between, space-around, and space-evenly.
        

      


      

        
          What is the difference between align-items and align-self?
          ▼
        
        

          align-items is set on the flex container and controls the default cross-axis alignment for all children. align-self is set on an individual child and overrides that default for just that item.
