CSS3 анимация для ширины в различном%

Question

Я использовал CSS3 анимацию для расширения полосы, но вопрос заключается в том, что PRECENTAGE должен быть вставлен в @ KeyFrames-коду. В HTML пользовательская ширина вставляется как встроенный css.

Есть ли способ анимировать размер вложенной ширины CSS, а не то, что вставлено в файл @keyframe?

#dataanalysis td figure { 
 
    animation: aw 2s normal;

Необходимо только, чтобы удалить 100% часть анимации из @keyframes, заключительный этап анимации, как представляется, происходит от width множества в атрибуте в линию style:

#dataanalysis td figure { 
 
    animation: aw 2s normal; 
 
} 
 
@keyframes aw { 
 
    0% { 
 
    width: 0%; 
 
    } 
 
} 
 
#dataanalysis { 
 
    width: 100%; 
 
    margin-top: 3rem; 
 
    background: #26272b; 
 
    color: white; 
 
    border-collapse: collapse; 
 
    font-size: .7rem; 
 
    font-weight: 300; 
 
    -webkit-font-smoothing: antialiased; 
 
} 
 
#dataanalysis td { 
 
    border: solid 1px black; 
 
    padding: .5rem; 
 
    word-wrap: break-word; 
 
    height: 25px; 
 
} 
 
#dataanalysis td:first-child { 
 
    width: 140px; 
 
    padding-left: .5rem; 
 
} 
 
/* Following rule simply to hide the broken images, 
 
    irrelevant to the answer/requirement */

Answer 2

Вместо ключевого кадра вы должны использовать transition. Что-то вроде:

#dataanalysis td figure { 
    transition: width 2s normal; 
}
