稍微改一下 createFilterButton() 就能完美融入B站风格，很难理解为什么使用目前的设计风格……

function createFilterButton(text, fType, callback) {
const button = document.createElement('button')
button.textContent = text
button.className = 'bil-filter-btn vui-button mr_sm vui_button--tab'
button.style.borderRadius = '6px'
button.onclick = function() {
nowTypeIndex = fType
btnList.forEach(btn => btn.classList.remove('vui_button--active'))
button.classList.add('vui_button--active')
mFilter(callback)
}
return button
}
