在此处输入图像描述

有这样一个输入，我不明白怎么可能让它通过边界，但是边缘变得很锋利

border-bottom-width: 2px
border-bottom-color: $black
border-bottom-style: solid
box-sizing: border-box
border-bottom-left-radius: 8px
border-bottom-right-radius: 8px

如果你通过渐变来做，那么笔画就会被切断。

我能做到的唯一方法是添加第二个元素，是否可以在不创建额外块的情况下制作它

如果你从手机打开它并尝试移动它，有一个滑块，然后它开始抽搐，我该如何修复这个 codePen

        let slide = document.querySelectorAll('.slide');
        let wrappedSlide = document.querySelector('.wrapped-slide');
        let slider = document.querySelector('.slider');

        let slideOne = slide[0];

        wrappedSlide.addEventListener('touchstart ', getCurCoordsInsideRect);
        wrappedSlide.addEventListener('mousedown', getCurCoordsInsideRect);

        function getCurCoordsInsideRect(event) {

            let sliderWidth = parseFloat(window.getComputedStyle(slider, null).getPropertyValue("width"));
            let wrappedSlideWidth = parseFloat(window.getComputedStyle(wrappedSlide, null).getPropertyValue("width"));
            let slidelWidth = parseFloat(window.getComputedStyle(slideOne, null).getPropertyValue("width"));

            event.preventDefault(); // предотвратить запуск выделения (действие браузера)

            let shiftX = event.clientX == undefined ?
                event.changedTouches[0].pageX - wrappedSlide.getBoundingClientRect().left :
                event.clientX - wrappedSlide.getBoundingClientRect().left;
            // shiftY здесь не нужен, слайдер двигается только по горизонтали

            document.addEventListener('mousemove', onMouseMove);
            document.addEventListener('mouseup', onMouseUp);

            function onMouseMove(event) {
                let newLeft = event.clientX == undefined ?
                    event.changedTouches[0].pageX - shiftX - slider.getBoundingClientRect().left :
                    event.clientX - shiftX - slider.getBoundingClientRect().left;

                // курсор вышел из слайдера => оставить бегунок в его границах.
                if (newLeft > 0) {
                    newLeft = 0;
                }

                let numberSlide = Math.floor(sliderWidth / slidelWidth) * slidelWidth;

                if (numberSlide <= 0) numberSlide = slidelWidth

                let rightEdge = (wrappedSlideWidth - numberSlide) * -1;
                if (newLeft < rightEdge) {
                    newLeft = rightEdge;
                }

                wrappedSlide.style.transform = `translateX(${newLeft}px)`;
            }

            function onMouseUp() {
                document.addEventListener('touchmove', onMouseMove);
                document.removeEventListener('mouseup', onMouseUp);
                document.removeEventListener('mousemove', onMouseMove);
