问题 Is there a way to select every nth child that matches (or does not match) an arbitrary selector ? For example, I want to select every odd table row, but within a subset of the rows: table.myClass tr.row:nth-child(odd) { ... } <table class="myClass"> <tr> <td>Row <tr class="row"> <!-- I want this --> <td>Row <tr class="row"> <td>Row <tr class="row"> <!-- And this --> <td>Row </table> But :nth-child() just seems to count all the tr elements regardless of whether or not they're of the "row"

问题 I'm trying to recreate the following image in CSS: I've already started making the box and arrow (see below) and now my only problem is to make the left edge of the arrow round with CSS only just like in the image.

问题 I have 6 bootstrap columns that contain a short description for each slick slide. Is it possible to replace the default slick slider dots with these columns? The most important part is that I want to keep the existent layout and not having them all inline like the default dots. jsfiddle demo As an example, when the slide 4 is active ( autoplay: true ), column 4 will have a red background color.

问题 This question is being asked out of cursosity. I've just noticed when I have this bit of markup: <div style="height: 20px; background-color: yellow;"> Test <br /> <br /> <br /> </div> The br tags have no effect. However, if the parent has no height i.e. height: auto - the br tags become effective - why is this the case? Is this the same in all cases i.e. across different doc types and browsers? 回答1: I think the <br> tags do have an effect. If I change your markup as follows: <div style=

问题 I'm currently looking to find a way to remove or hide the "Go to Definition" and "Go to References" options that display when a JS file is opened in monaco-editor as part of their built-in support, in favor of including custom options to go to definition and find references. I believe there's no public API to accomplish this, and my attempts to hide the options with CSS have been unsuccessful, so any pointers or help would be appreciated, thanks. 来源： https://stackoverflow.com/questions
