Vue2.x Class & Style Bindings

Intoduciton: The way of using '' in html part confused me when I was learning Class&Style Bindings in Vue's official guide.(of course it's also because of my weak foundation). To help newcomer understand, Vue's official guide seemed a little lengthy. So I decided to reorganize them.

  data: {
    data-key-styleObject: {
      color: 'red',
      fontSize: '13px'
    }
  }

• Array：:style="[styleObjects, overridingStyleObjects]"

  styleObjects means we could multiple "{}" and "data-key"

Advanced

• Multiple Values：:style="{ display: ['-webkit-box', '-ms-flexbox', 'flex'] }"

  This will only render the last value in the array which the browser supports. In this example, it will render display: flex for browsers that support the unprefixed version of flexbox.(Copy from Vue official guide)
