I was using the box-sizing method which I was hoping would make it say 100% including the margin but it does 100% PLUS the margin, meaning I have a vertical scroll bar. It's demonstrated here: http://jsbin.com/xomocitono/1 <div id="main"> Test </div> #main {width: 100%; margin-left: 100px; margin-right: 100px; background: red;} In my own particular situation I can't use the following: Padding instead, because even though it works how I want (in terms of 100%

This is my code for the toggle. appreciate any help .always is the checkbox $(document).ready(function () { $('.always').click(function () { $('#dates').toggle(); }); }); 回答1: .toggle() takes a boolean as well, like this: $(function () { $('.always').change(function () { $('#dates').toggle(!this.checked); }).change(); //ensure visible state matches initially }); You can test it out here . I assume in the above you want the #dates hidden if

Before form submit I run a validate routine to check if all the required fields are filled with some text. If not, a div with the class 'redAlert' gets visible right above the text field. I also want the dialog window to scroll right to this position when the error messages are displayed. I know there are quite a few plugins available for doing this but I want to do it using simple Jquery. I am trying to A) Find the first visible div with the class redAlert, b) Find its

fieldset 元素可将表单内的相关元素分组。 <fieldset> 标签将表单内容的一部分打包，生成一组相关表单的字段。<fieldset> 标签没有必需的或唯一的属性。 当一组表单元素放到 <fieldset> 标签内时，浏览器会以特殊方式来显示它们，它们可能有特殊的边界、3D 效果，或者甚至可创建一个子表单来处理这些元素。 <div> 可定义文档中的分区或节（division/section）。 <div> 标签可以把文档分割为独立的、不同的部分。它可以用作严格的组织工具，并且不使用任何格式与其关联。 如果用 id 或 class 来标记 <div>，那么该标签的作用会变得更加有效。 用法 <div> 是一个块级元素。这意味着它的内容自动地开始一个新行。实际上，换行是 <div> 固有的唯一格式表现。可以通过 <div> 的 class 或 id 应用额外的样式。 不必为每一个 <div> 都加上类或 id，虽然这样做也有一定的好处。 可以对同一个 <div> 元素应用 class 或 id 属性，但是更常见的情况是只应用其中一种。这两者的主要差异是，class 用于元素组（类似的元素，或者可以理解为某一类元素），而 id 用于标识单独的唯一的元素。 来源： https://www.cnblogs.com/kimij1602/p/11770801.html

I have a textarea with a transparent background overlaying some TEXT that I'd like to use as a sort of watermark. The text is large and takes up a majority of the textarea. It looks nice, the problem is when the user clicks in the textarea it sometimes selects the watermark text instead. I want the watermark text to never be selectable. I was expecting if something was lower in the z-index it would not be selectable but browsers don't seem to care about z-index layers when selecting items. Is
