Vuetify grid system row management

I spent quite a bit of time rearranging the Vuetify <v-col> and <v-row>, basically trying to separate the third column out by itself, so that blue could be shrunk and red could be grown.

It nearly worked, but some other features were lost (like the indigo's spanning their entire column and row-gutters disapearing). There seems to be some weird interaction between the fluid (snaking) layout and the <v-row> & <v-col> mechanism.

Also, the gutters have an disturbing wonkiness as you change page width.

Instead I got a fairly perfect result by switching to CSS grid - simpler and easier to adjust.

It's also smoothly responsive when you change page width.

HTML

First thing to note, no <v-row> or <v-col> elements, just the things you want to display. You can throw them on the page in any order (well, inside the container) and the CSS grid takes care of placement.

<div id="app">
  <v-app id="inspire">
    <v-container fluid class="myGrid">
      <v-card class="orange" color="orange lighten-2" tile flat>
        <v-card-text>Card 1</v-card-text>
      </v-card>
      <v-card class="indigo1" color="indigo lighten-2" dark tile flat>
        <v-card-text>Card 3 Extended To fit</v-card-text>
      </v-card>
      <v-card class="indigo2" color="indigo lighten-2" dark tile flat>
        <v-card-text>Card 3 Extended To fit</v-card-text>
      </v-card>
      <v-card class="indigo3" color="indigo lighten-2" dark tile flat>
        <v-card-text>Card 3 Extended To fit</v-card-text>
      </v-card>
      <v-card class="red" color="red lighten-2" dark tile flat>
        <v-card-text>
          {{ lorem }} {{ lorem }} 
          {{ lorem }}{{ lorem }} 
          {{ lorem }} {{ lorem }}
        </v-card-text>
      </v-card>
      <v-card class="purple" color="purple lighten-1" tile flat>
        <v-card-text>{{lorem}} {{lorem}}</v-card-text>
      </v-card>
      <v-card class="green" color="green lighten-2" tile flat>
        <v-card-text>{{lorem}} {{lorem}}</v-card-text>
      </v-card>
      <v-card class="blue" color="blue lighten-2" tile flat>
        <v-card-text>{{lorem}}</v-card-text>
      </v-card>
    </v-container>
  </v-app>
</div>

CSS

CSS grid areas allow you to define the grid in rows and columns, then assign elements (via a unique class) to the matrix.

As you get more tricky requirements, just add more rows or columns and spread elements over them (see grid-template-areas, the strings attached to that property represent the matrix).

.myGrid {
  display: grid;
  grid-template-columns: auto auto auto;         // 3 even self-sizing cols
  grid-template-rows: repeat(3, 1fr) auto auto;  // 5 rows, first 3 expand & last 2 shrink
  grid-template-areas: 
    "orange indigo1 red"
    "orange indigo2 red"
    "orange indigo3 red"
    "purple green red"
    "purple green blue"
    ;
  grid-gap: 0.5rem;
}
.orange { grid-area: orange }
.indigo1 { grid-area: indigo1 }
.indigo2 { grid-area: indigo2 }
.indigo3 { grid-area: indigo3 }
.red { grid-area: red }
.green { grid-area: green }
.purple { grid-area: purple }
.blue { grid-area: blue }
