我有一个pen,基本上是一个待办事项应用程序。待办事项实际上是具有文本,li
和button
的hr
元素。他们中有些人在hr
中有空格,而有些人则没有。

HTML:
const j = $;
j(() => {
let validify = txt => {
if (txt.length > 0) {
j('#ctn').append(`<li class='td'>${txt}<button class='td-btn'>Dismiss</button><hr/></li>`);
}
j('.td-btn').on('mouseenter', function() {
console.log('added');
j(this)
.parent()
.addClass('del');
console.log(j(this).parent().attr('class'))
}).on('mouseleave', function() {
console.log('removed')
j(this)
.parent()
.removeClass('del');
}).on('click', function() {
j(this).parent().css('display', 'none');
});
j('#addtd').val('');
}
validify('');
j('#btn').on('click', () => {
validify(j('#addtd').val());
});
});

谁能解释我为什么会这样?
最佳答案
这是由于CSS Sub像素渲染而发生的。
当您放大/缩小浏览器时,重新缩放的元素将剩下5.75px等像素值。供应商决定如何处理。
在您的情况下,最简单的解决方法(至少在Chrome中是)将边框半径取消为0px,而是将hr的高度设置为边框的两倍,并为其提供背景颜色:
border: 0px solid #9E9D24;
padding: 0;
height: 14px;
background: #9E9D24;
