我如何最初将幻灯片容器设置为距左边距 10%，当到达末端时，距右边距 10%？ （vue-awesome-swiper）

Question

This is probably an easy question but I can't seem to find a solution to this..

I am using vue-awesome-swiper( https://github.surmon.me/vue-awesome-swiper/ ). I would like to have something like this:

Initial margin on the left by 10%:

When the inner slides are visible, they are touching left and right(full width stretch):

When the last slide is reached, a margin-right of 10%:

Examples can be found here: https://github.surmon.me/vue-awesome-swiper/ .

I added margin-left:10%; to the swiper-wrapper class which works for me as the initial margin, but this covers my last slide as the content is shift by 10%. I would like margin-left to be removed when the last slide is reached and vice versa.

I tried looking at events( https://swiperjs.com/api/#events ): reachEnd and reachBeginning . Both of these, I tried to apply like this:

<template>
<div>
      <swiper
        class="swiper"
        :options="swiperOption"
        :reach-beginning="handleTransitionStart"
        :reach-end="handleTransitionEnd"
        :style="transitionStarted ? { margin: '0 0 0 10%' } : { margin: '0 10% 0 0' }"

      >
.....
</swiper>
</div>
</template>

<script lang="ts">
import { Component, Prop, Vue } from 'vue-property-decorator';

@Component
export default class InformationSection extends Vue {
  @Prop() 'reachEnd'!: any;
  @Prop() 'reachBeginning'!: any;

  swiperOption = {
    slidesPerView: 4,
    spaceBetween: 30,
    pagination: {
      el: '.swiper-pagination',
      clickable: true,
    },
  };

  transitionStarted: boolean = true;

  handleTransitionStart(): any {
    // eslint-disable-next-line no-console
    console.log('Started');
    this.transitionStarted = true;
  }

  handleTransitionEnd(): any {
    // eslint-disable-next-line no-console
    console.log('Ended');
    this.transitionStarted = false;
  }
}
</script>

<style scoped>

  .swiper-slide {
    width: 60%;
  }
  .swiper-slide:nth-child(2n) {
      width: 40%;
  }
  .swiper-slide:nth-child(3n) {
      width: 20%;
  }

</style>

The above does not add margin to the right at the end. How can I achieve this goal?

I recall needing something similar and ended up building my own scroller component. But that's not for everyone.

There's a hacky way to do it, and I hope you find something cleaner.

The first slide has a margin <swiper-slide style="margin-left:10%;">I'm Slide 1</swiper-slide>

and the last slide is invisible <swiper-slide style="opacity:0;"></swiper-slide>

 Vue.use(VueAwesomeSwiper) new Vue({ el: '#vueapp', components: { LocalSwiper: VueAwesomeSwiper.swiper, LocalSlide: VueAwesomeSwiper.swiperSlide, }, data: { swiperOptionA: { slidesPerView: 4, spaceBetween: 30, pagination: { el: '.swiper-pagination', clickable: true, }, navigation: { nextEl: '.swiper-button-next', prevEl: '.swiper-button-prev' } }, }, computed: { swiperA() { return this.$refs.awesomeSwiperA.swiper }, }, })

 .swiper-container { height: 300px; width: 100%; }.swiper-slide { text-align: center; font-size: 38px; font-weight: 700; background-color: #eee; display: -webkit-box; display: -ms-flexbox; display: flex; -webkit-box-pack: center; -ms-flex-pack: center; justify-content: center; -webkit-box-align: center; -ms-flex-align: center; align-items: center; }

slidesOffsetAfter

slidesOffsetBefore

Ref: https://swiperjs.com/swiper-api#param-slidesOffsetAfter

if($('.swiper').length !== 0){
const swiper = new Swiper('.swiper', {
    loop: false,
    slidesOffsetBefore: 5, // This is 5px slide offset 
    slidesPerView: 1.3,  // second slide partial show (In this question it was probably 3.5)
    centeredSlides: true // centering slides
    spaceBetween: 10,
  }
});}

The way I achieved this is to set the overflow property of .swiper-container to visible, place it inside a div that has the required margin, and give another outer div the property of overflow: hidden like so:

<div style="overflow: hidden">
    <div style="margin: 0 1rem">
        <div class="swiper-container" style="overflow: visible">
            <!-- ... -->
        </div>
    </div>
</div>

There may also be another way which is to set the width of .swiper-container less than 100% and ensure it is centred inside the parent element, but I haven't tried it out.

The problem I faced is a bit different, because it's not percentage but a mere 32px of margin left. I solved it by doing just css of these:

.swiper-wrapper {
  margin-left: 32px;
}

.swiper-wrapper .swiper-slide:last-child{
  padding-right: 32px;
}

If I only add the margin-left to the.swiper-wrapper, the last slide will be cut 32px, hence I add the last slide to be 32px more wider by adding a padding-right. Similar approach is you can use margin-right or:after selector to make the last slide wider.
