html - Run a chain animation on different selectors by clicking once on a button -


I'm trying to run 2 CSS3 animations by clicking on a button. The first animation button rotates and disappears, and the second animation changes the second button, and it looks (the opacity has been changed from 0.5 to 1) and changes its height.

The problem is that only the first animation runs. The first animation name is

q1leave

and the other is the animation name

q2show P> To run the first animation I use the # btnq1: target on the CSS and I to run the second animation I # btnq1: target # btnq2a

See my code below:

HTML code 

  & lt; Div id = "q1" & gt; & Lt; Div class = "q1once" & gt; & Lt; A href = "# btnq1" & gt; & Gt; Button type = "button" name = "" value = "" id = "btn q1" & gt; Click to disappear, and then a different element & lt; / Button & gt; & Lt; / A & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Button type = "button" name = "" value = "" id = "btnq2a" & gt; & Gt; & Gt; Button & gt;   
 CSS code  
  # q1 {height: 100%; } .q1once {width: 20%; Height: 15%; Status: Completed; Left: -50%; Animation Name: Q1; Animation-Delay: 3s; Animation- Count of Travel: 1; Animation-period: 1.5s; Animation Fill-Mode: Forward; } #BTN1: Goal {Animation-Name: q1leave; Animation- Count of Travel: 1; Animation-period: 4s; Animation Fill-Mode: Forward; } # BTNA1: Target # BTNK2A Animation-Name: Q2Show; Animation- Count of Travel: 1; Animation-Delay: 4s; Animation-period: 4s; Animation Fill-Mode: Forward; } @ Keyframes Q1 {50% {Conversion: Translation (440%) Scale (3); } 100% {conversion: translation (450%) scale (1.5, 2); }} @ Keyframe q1leave {0% {transform: rotate (0deg); Opacity: 1; } 100% {Opacity: 0; As a result rotate (360deg); }} @ Keyframe q2show {100% {Opacity: 1; Height: 200px; }} # Btnk2a {opacity: 0.5; }   
 You can also do with me, I want to solve it using only CSS3, but I will accept other solutions using JS, jquery or other. What am i doing wrong   
 
 
 Javascript will be the easiest way to add a square to the second goal whenever the first click is clicked. is.  
  var btn1 = document.getElementById ('btnq1'); Var btn2 = document.getElementById ('btnq2a'); Btn1.addEventListener ('Click, MakeActive); Function MakeActive () {var className = '' + btn2.className + ''; // SO SO Question # 14615712 if (~ className.indexOf ('active')) {btn2.className = className.replace ('active', ''); } And {btn2.className + = 'active'; }}   
 or jQuery if you want:  
  $ ('# btnq1'). ('Click', function () {$ ('# btnq2a'). ToggleClass ('active');});   
 Then, adjust your CSS selector a bit.  
  # btnq2a.active {animation-name: q2show; Animation- Count of Travel: 1; Animation-Delay: 4s; Animation-period: 4s; Animation Fill-Mode: Forward; }

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number".

Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
