Frequently Asked Questions
Use flexbox for one-dimensional layouts — a single row or column, such as a navbar or a row of buttons. Use CSS grid for two-dimensional layouts where rows and columns matter together, such as page layouts and card galleries. They combine well: a grid page can hold flexbox components.
Make the parent a flex or grid container and center its content: display: grid; place-items: center; works in one line. The CSS Centering Generator gives you the right method for horizontal, vertical or both, including absolute positioning.
Padding is the space inside an element, between its content and its border, and it takes the element's background. Margin is the space outside the border that pushes other elements away. The Spacing Generator previews both and outputs the shortest shorthand.
