为什么我的右浮动元素留下来了越来越多的

问题描述 投票:1回答:2

我通过一个待办事项列表教程工作我的方式。它正常工作,直到我试图样式它一点点。我有一个字体真棒垃圾桶可以用类“删除”按钮的图标内。基本上,我把所有的款式关闭按钮,它只是垃圾桶图标。用户点击它,并有待办事项列表项删除,因为它应该。我想立刻从弹出的任务对齐垃圾桶。它确实如此,但每次我添加新任务垃圾桶浮动权越来越少。

生病尝试只是张贴相关的代码,但我不知道为什么会这样。我使用的是引导,帮助风格和和的加号按钮,圆形似乎并不与任务进行干扰,因为他们创建的。任何想法将是真棒,谢谢大家!

Here is a pic

function get_todos() {
    var todos = new Array;
    var todos_str = localStorage.getItem('todo');
    if (todos_str !== null) {
        todos = JSON.parse(todos_str); 
    }
    return todos;
}
 
function add() {
    var task = document.getElementById('task').value;
 
    var todos = get_todos();
    todos.push(task);
    localStorage.setItem('todo', JSON.stringify(todos));
 
    show();
 
    return false;
}
   




//This is mostly where the remove button takes place 


function remove() {
    var id = this.getAttribute('id');
    var todos = get_todos();
    todos.splice(id, 1);
    localStorage.setItem('todo', JSON.stringify(todos));
 
    show();
 
    return false;
}
 
function show() {
    var todos = get_todos();
 
    var html = '<ul>';
    for(var i=0; i < todos.length; i++) {
        html += '<li>' + todos[i] + '<button class="remove" id="' + i  + '"><i class="fa fa-trash" aria-hidden="true"></i></button></li>';
    };
    html += '</ul>';
 
    document.getElementById('todos').innerHTML = html;
 
    var buttons = document.getElementsByClassName('remove');
    for (var i=0; i < buttons.length; i++) {
        buttons[i].addEventListener('click', remove);
    };
}
 
document.getElementById('add').addEventListener('click', add);
show();
 .remove { /*Trash can button*/
	color:#C0C0C0;
	font-size:24px;
	border:0;
	padding:0;
	background-color:transparent;
	float:right;

这是因为它上面的浮动元素是在路上。避免这种情况的一种方法是clear: rightclear: both添加到样式的浮动元素。

.remove { /*Trash can button*/
    color:#C0C0C0; 
    font-size:24px;
    border:0;
    padding:0;
    background-color:transparent;
    float:right;
    clear:right;
}

我打周围的CSS,发现下面的CSS样式工作。修正,见下面的变化。这将使该列表看起来更漂亮。

<ul>元素

font-size: 20px;

上卸下摆臂类

去掉

font-size: 24px;
float:right;

position: absolute;
right: 20px;
