does angular material have a grid system?

This site describes how to add the bootstrap grid to a Angular Material project: https://www.amadousall.com/the-good-parts-of-bootstrap-4-you-are-missing-in-your-angular-material-projects/

A summary of the steps described in the article:

Add bootstrap to your project:

npm install bootstrap --save

src/styles.scss:

@import '~@angular/material/prebuilt-themes/indigo-pink.css';

@import 'variables';

// Imports functions, variables, and mixins that are needed by other Bootstrap files
@import '~bootstrap/scss/functions';
@import '~bootstrap/scss/variables';
@import '~bootstrap/scss/mixins';
// Import Reboot
@import '~bootstrap/scss/reboot';
@import '~bootstrap/scss/grid'; // add the grid
@import '~bootstrap/scss/utilities'; // add css utilities

@import 'reset';

src/_variables.scss:

The _variables.scss Sass partial allows us to customize Bootstrap - more precisely, the parts of Bootstrap that we will be using

$link-color: #3f51b5;
$link-hover-color: currentColor;
$link-hover-decoration: none;

$grid-breakpoints: (
  xs: 0, // handset portrait (small, medium, large) | handset landscape (small)
  sm: 600px, // handset landscape (medium, large) | tablet portrait(small, large)
  md: 960px, //  tablet landscape (small, large)
  lg: 1280px, // laptops and desktops
  xl: 1600px // large desktops
);

$container-max-widths: (
  sm: 600px,
  md: 960px,
  lg: 1280px,
  xl: 1600px
);

src/_reset.scss:

The _reset.scss Sass partial allows us to override some of the Bootstrap styles we don't want

* {
  &:active,
  :focus {
    outline: none !important;  // 1
  }
}

label {
  margin-bottom: 0; // 2
}


a:not(.mat-button):not(.mat-raised-button):not(.mat-fab):not(.mat-mini-fab):not([mat-list-item]) {
  color: #3f51b5; // 3
}

If you are using Material2, you can use Angular Flex Layout for responsiveness. It compliments Angular2 well and is lightweight.

Basically Material2 + Flex-layout is equivalent to Bootsrap library.

Here's an example of how flex-layout can be used for grid system/responsiveness with Angular/Material2.

Sample Code showing use of flex-layout API:

<div fxShow.xs="true" fxShow="false" >Screen size <h1>XS</h1></div>
    <div fxShow.sm="true" fxShow="false" >Screen size <h1>SM</h1></div>
    <div fxShow.md="true" fxShow="false" >Screen size <h1>MD</h1></div>
    <div fxShow.lg="true" fxShow="false" >Screen size <h1>LG</h1></div>
    <div fxShow.xl="true" fxShow="false" >Screen size <h1>XL</h1></div>

    <div fxLayout="row" 
         fxLayout.xs="column"
         fxLayoutGap="10px"
         fxLayoutAlign.xs="center center"
         fxLayoutWrap>
      <div class="sample-div" fxFlexOrder.lt-md="7">Div 1</div>
      <div class="sample-div" fxFlexOrder.lt-md="6">Div 2</div>
      <div class="sample-div" fxFlexOrder.lt-md="5">Div 3</div>
      <div class="sample-div" fxFlexOrder.lt-md="4">Div 4</div>
      <div class="sample-div" fxFlexOrder.lt-md="3">Div 5</div>
      <div class="sample-div" fxFlexOrder.lt-md="2">Div 6</div>
      <div class="sample-div" fxFlexOrder.lt-md="1">Div 7</div>
      <div class="sample-div" fxFlexOrder.lt-md="0">Div 8</div>
    </div>
