採用postcss的Autoprefixer插件,便可知足大多數oppo,vivo手機的兼容性問題。

transform 屬性向元素應用 2D 或 3D 轉換。該屬性容許咱們對元素進行旋轉、縮放、移動或傾斜。
其中 transform-origin (屬性改變被轉換元素的中心)。
三者區別: animation 動畫,關鍵幀,往復性。 transition 過渡, 屬性,觸發動做,一過性。 transform 變換, 複雜的變換參數。
改變位置translate3d
,透明度opacity
和大小scale
。
流星尾巴採用僞元素元素:after
旋轉-45deg
(旋轉基點爲左transform-origin: left;
);採用border
能夠實現,靠近頭部越亮,靠近尾部越暗。
.star { display: block; width: 5px; height: 5px; border-radius: 50%; background: #FFF; top: 10px; left: 200px; position: relative; animation: star-ani 6s infinite ease-out; box-shadow: 0 0 5px 5px rgba(255, 255, 255, .3); opacity: 1; } .star:after { content: ''; display: block; top: 0px; left: 40%; border: 0px solid #fff; border-width: 0px 90px 2px 90px; border-color: transparent transparent transparent rgba(255, 255, 255, .3); transform: rotate(-45deg) translate3d(1px, 3px, 0); box-shadow: 0 0 1px 0 rgba(255, 255, 255, .1); transform-origin: left; } @keyframes star-ani { 0% { opacity: 0; transform: scale(0) rotate(0) translate3d(0, 0, 0); } 50% { opacity: 1; transform: scale(1) rotate(0) translate3d(-100px, 100px, 0); } 100% { opacity: 0; transform: scale(1) rotate(0) translate3d(-200px, 200px, 0); } }
改變透明度
.shine { background: url('../../../../images/action/icon-star1.png') no-repeat center; background-size: 100%; width: 30px; height: 40px; position: absolute; top: 90px; left: 100px; opacity: 0; animation: opacity-change 0.5s ease-in-out infinite; } @keyframes opacity-change { 0% { opacity: 0; } 50% { opacity: 1; } 100% { opacity: 0; } }
分爲兩段動畫,降低和上升。
translateY
改變便可。
.text-item-0 { position: absolute; width: 25px; height: 75px; top: 60px; left: 100px; background: url('../../../../images/action/S-start.png') no-repeat center; background-size: 100%; animation: letter-0 1.5s ease-in-out both, letter-0-1 2.0s ease-in-out 1.5s both; } @keyframes letter-0 { 0% { transform: translateY(0) } 50% { transform: translateY(80px) } 100% { transform: translateY(0px) } } @keyframes letter-0-1 { 0% { opacity: 1; } 100% { top: -80px; opacity: 0; } }
切換dom,添加類控制移動和暫停,以及切換背景人物。監聽
animationend
事件。
jsx { peopleMove ? <div className={`${style.people_move} ${!pausedState && style.people_paused}`} ref={start2 => { this.start2 = start2 }} /> : <div className={style.people} /> } css .people { width: 20px; height: 64px; position: absolute; left: 10px; top: 130px; background: url('../../../../images/action/people.png') no-repeat center; background-size: 100%; opacity: 0; animation: peopleUp 1s ease-in-out 0.5s both; } .people_move { background: url('../../../../images/action/people_moveleft.gif'); background-size: 100% 100%; background-position: center; background-repeat: no-repeat; width: 20px; height: 64px; position: absolute; left: 10px; top: 130px; opacity: 1; animation: PeopleMove 1.5s linear 0s both; } .people_paused { width: 20px; height: 64px; background: url('../../../../images/action/people.png'); background-size: 100% 100%; background-position: center; background-repeat: no-repeat; animation-play-state: paused; } @keyframes peopleUp { 0% { opacity: 0; } 100% { opacity: 1; } } @keyframes PeopleMove { 0% { left: 10px; top: 130px; } 100% { top: 20px; left: 180px; background-size: 100% 100%; background-position: center; background-repeat: no-repeat; } } // 監聽動畫結束時機 componentDidUpdate() { const { peopleMove } = this.state if (peopleMove) { this.start2.addEventListener('animationend', this.end) this.start2.addEventListener('webkitAnimationEnd', this.end) this.start2.addEventListener('mozAnimationEnd', this.end) this.start2.addEventListener('oAnimationEnd', this.end) } }
配合
background-size: cover;
屬性實現。
.brige { width: 0px; background: url('../../../../images/action/bridge.png'); background-size: cover; background-repeat: no-repeat; height: 100px; position: absolute; top: 40px; left: 30px; animation: BridgeFadeIn 3s linear both; opacity: 0; } @keyframes BridgeFadeIn { 0% { width: 0px; opacity: 0; } 100% { width: 200px; opacity: 1; } }
利用
transform scale
2D 縮放轉換。
.icon-ciecle { display: block; position: absolute; left: 100px; top: 80px; width: 30px; height: 30px; background: url('../../../../images/action/icon-light.png') no-repeat center; background-size: 100%; animation: warn 1.2s ease-in-out 0s infinite both; } @keyframes warn { 0% { transform: scale(0.1); opacity: 0.0; } 25% { transform: scale(0.2); opacity: 0.3; } 50% { transform: scale(0.4); opacity: 0.5; } 75% { transform: scale(0.6); opacity: 0.7; } 100% { transform: scale(0.8); opacity: 0.0; } }
ios的animation-play-state: paused;
不起做用,且animation
動畫不可寫在新增類裏,必須寫在一個類裏。(測試中發現,這裏有疑問。)
.music_img { width: 40px; height: 40px; display: block; position: absolute; left: 100px; top: 80px; animation: rotating 3s linear infinite; animation-play-state: running; } .rotate-pause { animation-play-state: paused; } @keyframes rotating { 0% { transform: rotate(0deg); } 100% { transform: rotate(360deg); } }
Swiper的react版本,基本api都支持,具實驗目測至關於Swiper v4。html
- 不必定經過api。也能夠經過重寫css實現。
- 重寫css切換效果的話,會影響它自己的動畫效果,因此可經過添加不可滑動來控制。
1. .swiper-wrapper { transition-delay: 1.6s; } 2. noSwiping: true, noSwipingClass: 'stop-swiping',
1.swiper的effect
屬性與控制背景圖片的opacity
,利用時間差實現最終效果。包括迷宮的切換,揹包男的出現與消失,彈窗的出現與消失。
2.swiper屬性的activeIndex
,能夠獲得滑動到第幾頁,經過改變dom
或者改變類,控制第幾頁動畫的發生。
// 根據activeIndex拿到的頁數,控制該頁數state的改變,經過切換dom和添加類的方式,達到進場與退場的動畫效果。 // 添加類stop-swiping控制不可滑動,動畫完成後,纔可繼續滑動下一頁。 const mazeStyle = classNames({ [styles['maze-1']]: true, [styles['maze-out']]: firstMazeOut, }) const peopleStyle = classNames({ [styles['people-1']]: true, [styles['people-out']]: firstMazeOut, }) const popCardStyle = classNames({ [styles['pop-card-container']]: true, [styles['pop-card-out']]: firstMazeOut, }) { firstMazeIn ? <div className={!isSlideFirst && "stop-swiping"}> <div className={styles['maze-container']}> <div className={mazeStyle} /> <div className={peopleStyle} /> </div> <div className={popCardStyle}> <ModalScene {...this.props} /> </div> </div> : <div /> // 不添加會影響swiper自身頁數的判斷 }
別人寫的真牛X,本身只會opacity
,translate
。
