ts报错 ts:Property ‘style‘ does not exist on type ‘Element‘.

problem

ts报错 ts:Property ‘style’ does not exist on type ‘Element’.

firstEle.style.flexGrow = 1

reason

style 不是 Element 的属性

solution

const firstEle:HTMLElement = document.querySelector('.accordion-item')!
firstEle["style"].flexGrow = '1'
