I have div tag containing several ul tags. div ul If I trying set CSS properties only for the first ul tag, and this code works: ul div ul:first-child background-color: #900; When I want set CSS properties for each ul tag except the first, I tried this: ul div ul:not:first-child background-color: #900; also this: div ul:not(:first-child) background-color: #900; and this: div ul:first-child:after background-color: #900; But to no effect. How must I write in CSS: "each element, except the first"? 6 Answers 6 One of the versions you posted actually works for all modern browsers (where CSS selectors level 3 are supported): div ul:not(:first-child) background-color: #900; If you need to support legacy browsers, or if you are hindered by the :not selector's limitation (it only accepts a simple selector as an argument) then you can use another technique: :not Define a rule that has g...

Clash Royale CLAN TAG #URR8PPP Can I add a channel to a specific conda environment? I want to add a conda channel to a specific conda environment but when I use conda config --add channels glotzer that channel is now available from all my conda environments. In addition to testing an install from another environment, the ~/.condarc file has the following: ~/.condarc channels: - glotzer - defaults How would I configure conda so the channel is only available from a specific environment? I did find in the channel documentation that for conda >= 4.1.0, putting channels at the bottom of the ~/.condarc will prevent added channels from overiding the core package set. ~/.condarc By default conda now prefers packages from a higher priority channel over any version from a lower priority channel. Therefore you can now safely put channels at the bottom of your channel list to provide additional packages that are not in the default channels, and still be confident that these channels...

Clash Royale CLAN TAG #URR8PPP Memory Management in Windows Forms Application : Loading and Closing Forms This is my first time asking on a forum... An advanced apology if I'm too detailed... I have created a program that loads some forms (like a menu for a system) and a part of the program (a form) displays the contents of a table in a database in a listview (this part is working fine). When I access that form at the start of the program, it finishes loading for about 4-5 seconds. Here's the problem... When I access parts of the program a lot of times (e.g. going back and forth around two forms) then I access the form that displays the table, the loading gets slower... InitializeComponent(); //I just did this to travel back and forth to two forms easier... if (MessageBox.Show("", "", MessageBoxButtons.OKCancel, MessageBoxIcon.Information, MessageBoxDefaultButton.Button1) == DialogResult.OK) Form2 f = new Form2(); this.Hide(); f.ShowDialog(); thi...

Clash Royale CLAN TAG #URR8PPP Angular Material 2 Tabs with fixed (sticky) tab labels I have a layout using Angular Material 2 mat-sidenav layout with a mat-tab layout in the mat-sidenav-content section. I am trying to make the mat-tab-labels sticky so they are always visible, and still allow the dynamic tab-content to scroll. I can get the labels to stay fixed by setting overflow: hidden on the mat-sidenav-content and then set overflow: scroll on the mat-tab-body-wrapper element, but I have to set a fixed height to get the tab-content to scroll, but I have dynamic content so a fixed height isn't an option. Is there a way I can get my sticky labels and scrolling too without setting a fixed height? mat-sidenav mat-sidenav-content mat-tab-labels overflow: hidden mat-sidenav-content overflow: scroll mat-tab-body-wrapper tab-content Below is a demo.

Clash Royale CLAN TAG #URR8PPP How to handle weirdly combined websocket messages? I'm connecting to an external websocket api using the node ws library (node 10.8.0 on Ubuntu 16.04). I've got a listener which simply parses the json and passes it to the callback: this.ws.on('message', (rawdata) => let data = null; try data = JSON.parse(rawdata); catch (e) console.log('Failed parsing the following string as json: ' + rawdata); return; mycallback(data); ); I now receive errors in which the rawData looks as follows (I formatted and removed irrelevant contents): rawData �~A "id": 1, etc.. �~� { "id": 2, etc.. I then wondered; what are these characters? Seeing the structure I initially thought that the first weird sign must be an opening bracket of an array ( [ ) and the second one a comma ( , ) so that it creates an array of objects. [ , I then investigated the problem further by writing the rawdata to a file whenever it enco...
