  + Assuming the <a href="#quickstart">quickstart</a> template is in place, add the align property to the options object and pass it to Embla Carousel. Aligning slides only makes sense for slides smaller than 100% of the carousel viewport, so change the slide sizes to anything below 100%. The example below uses 80%.

  ```javascript
  const options = { align: 'start' }
  const embla = EmblaCarousel(emblaNode, options)
  ```
  +```css
  +.embla__slide {
  + flex: 0 0 80%;
