# Grid layout
This chapter is about the technical background of the dynamic grid system which visualizes grids and grid elements in AsTeRICS Grid.
The implementation using the GridList library (opens new window) was replaced by vue-css-grid-layout (opens new window), see issue #451 (opens new window).
For convenience reasons vue-css-grid-layout is developed directly within AsTeRICS Grid in folder src/vue-components/grid-layout, the vue-css-grid-layout (opens new window) contains a copy in order to be usable as standalone library in other projects.
See detailed docs (opens new window) in the Readme vue-css-grid-layout repository.
