Answer : 1- You should remove the mat-accordion to enable multiple expanded panels. 2- Use the expanded parameter to change multiple states at the same time. Here is a running example. EDIT From version 6.0.0-beta-0 you can use multi parameter and the openAll and closeAll functions : 1- Change the mat-accordion element to set the muti to true and get the MatAccordionComponent instance : <mat-accordion #accordion="matAccordion" [multi]="true"> 2- Then use the openAll and closeAll functions to open or close all panels : <button (click)="accordion.openAll()">Expand All </button> <button (click)="accordion.closeAll()">Collapse All </button> Here is a running example.

Example 1: descendent selector in css The descendant combinator — typically represented by a single space ( ) character — combines two selectors such that elements matched by the second selector are selected if they have an ancestor ( parent , parent 's parent, parent' s parent's parent , etc ) element matching the first selector . example : h1 ul { border : 1 px solid #f1f1f1 ; } Explanation : This above CSS code snippet will select all the 'ul' ( unordered list ) tags which are preceeded by an 'h1' ( header tag ) . /*the best way to understand is to practice by implemetation. Create a html file with lots of h1 and ul elements to understand by implementing CSS on them*/ Example 2: css select descendant with class Select an element with the ID "id" and the class "class" : # id . class { } example : < div > < strong id = "id" class = "class" > Foobar ...

Answer : I will just add to Gilles' answer by saying that although you may use “ cp , rsync , etc.” to transfer your read-only subvolumes / snapshots, you may also send and store the subvolumes as btrfs streams using the btrfs send command. The btrfs Wiki mentions the following use: # btrfs subvolume snapshot -r / /my/snapshot-YYYY-MM-DD && sync # btrfs send /my/snapshot-YYYY-MM-DD | ssh user@host btrfs receive /my/backups # btrfs subvolume snapshot -r / /my/incremental-snapshot-YYYY-MM-DD && sync # btrfs send -p /my/snapshot-YYYY-MM-DD /my/incremental-snapshot-YYYY-MM-DD | ssh user@host btrfs receive /backup/home but you may also just save the streams for future use: # btrfs subvolume snapshot -r / /my/snapshot-YYYY-MM-DD && sync # btrfs send /my/snapshot-YYYY-MM-DD | ssh user@host 'cat >/backup/home/snapshot-YYYY-MM-DD.btrfs' # btrfs subvolume snapshot -r / /my/incremental-snapshot-YYYY-MM-DD && sync # btrfs send -p /my...

Example 1: bootstrap Margin and padding Use the margin and padding spacing utilities to control how elements and components are spaced and sized. Bootstrap 4 includes a five-level scale for spacing utilities , based on a 1 rem value default $spacer variable. Choose values for all viewports ( e.g. , .mr-3 for margin-right : 1 rem ) , or pick responsive variants to target specific viewports ( e.g. , .mr-md-3 for margin-right : 1 rem starting at the md breakpoint ) . <div class= "my-0 bg-warning" >Margin Y 0 </div> <div class= "my-1 bg-warning" >Margin Y 1 </div> <div class= "my-2 bg-warning" >Margin Y 2 </div> <div class= "my-3 bg-warning" >Margin Y 3 </div> <div class= "my-4 bg-warning" >Margin Y 4 </div> <div class= "my-5 bg-warning" >Margin Y 5 </div> <div class= "my-auto bg-warning" >Margin Y Auto</div> ...

Answer : Simply add a div within col-md-6 that has the extra padding that you need. The col-md-6 is the 'backbone' to keep the column integrity, but you can add additional padding within it. <div class="row"> <div class="text-center col-md-6"> <div class="classWithPad">Widget 1</div> </div> <div class="text-center col-md-6"> <div class="classWithPad">Widget 2</div> </div> </div> CSS .classWithPad { margin:10px; padding:10px; } Update 2018 Bootstrap 4 now has spacing utilities that make adding (or substracting) the space (gutter) between columns easier. Extra CSS isn't necessary . <div class="row"> <div class="text-center col-md-6"> <div class="mr-2">Widget 1</div> </div> <div class="text-center col-md-6"> <div c...

Answer : So remove the setTimeout part. It will call resolve or reject and then pass the execution to the next then or catch handler. If you have some asynchronous call in the Promise, you need to call resolve/reject in the result of that call. What about not waiting 1500ms - the given time is actually the lowest time after which the function may be called. Maybe after 2000ms This is related to the main thread in which JS code works. If main thread has no work to done, then the results of the asynchronous calls are going to be executed. function f1() { return new Promise((resolve, reject) => { console.log('f1'); resolve(); }); } function f2() { console.log('f2'); } f1().then(res => f2()); If f1 is synchronous , there is nothing special to do: global() { f1(); f2(); } If f1 is asynchronous and return an Observable , use Rxjs operator , like concatMap: global() { f1().concatMap(() =>...

Answer : You should do a one-time setup of creating an " App password " in Bitbucket web UI with permissions to at least read your repositories and then use it in the command line. How-to: Login to Bitbucket Click on your profile image on the right (now on the bottom left) Choose Bitbucket settings (now Personal settings ) Under Access management section look for the App passwords option (https://bitbucket.org/account/settings/app-passwords/) Create an app password with permissions at least to Read under Repositories section. A password will be generated for you. Remember to save it, it will be shown only once! The username will be your Google username. Solved: Went on the log-in screen and clicked forgot my password . I entered my Google account email and I received a reset link. As you enter there a new password you'll have bitbucket id and password to use. Sample: git clone https://<bitbucket_id>@bitbucket.org/<repo> It's M...

Answer : You can remove a query parameter by using the merge option of queryParamsHandling and passing in null for any params you wish to remove. // Remove query params this.router.navigate([], { queryParams: { 'yourParamName': null, 'youCanRemoveMultiple': null, }, queryParamsHandling: 'merge' }) This option is simpler and requires less work to ensure you are not removing other params. You also do not need to worry about cleaning up an observable subscription when your component is destroyed. UPDATE: @epelc's answer below is the up-to-date and correct way to do this: https://stackoverflow.com/a/52193044/5932590. Unfortunately, there is no clear-cut way to do this currently: https://github.com/angular/angular/issues/18011. However, as jasonaden commented on the linked thread, This could be done manually by merging the old and new query params, removing the key you don't want. Here is one way to do that: Let's say...
