Use the animation-fill-mode property with the value both to extend the animation properties in both directions.ExampleLive Demo div { width: 150px; height: 200px; position: relative; background: red; animation-name: myanim; animation-duration: 2s; animation-fill-mode: both; } @keyframes myanim { from {left: 0px; background-color: green;} to {left: 200px; background-color: blue;} }
To set the fill-mode for an animation with CSS, use the animation-fill-mode property. It has the values forwards, backward, both for both the directions, etc.You can try to run the following code to set the fill-mode for animation;ExampleLive Demo div { width: 150px; height: 200px; position: relative; background: red; animation-name: myanim; animation-duration: 2s; animation-fill-mode: forwards; } @keyframes myanim { from {left: 0px; background-color: green;} to {left: 200px; background-color: blue;} }
C++11 was the modern C++ standard published in 2011. This brought many major extensions and improvements to the existing language. Following are the major changes/additions of C++11 −Initializer listsAutomatic type deductionRvalue references and move constructorsconstexpr – Generalized constant expressionsModification to the definition of plain old dataUniform initializationRange-based for loopLambda functions and expressionsAlternative function syntaxExplicit overrides and finalA constant null pointer, nullptrStrongly typed enumerationsRight angle bracket not being treated as an operator at appropriate placesVariadic templatesMultithreading memory modelAdded Hash tables to the STLAdded Regular expressions to the Standard LibraryAdded General-purpose smart pointers like shared_ptr, weak_ptr, etcAnd many more. You can get ... Read More
Use the animation-timing-function property, with the ease-in-out value to set animation with a slow start and end with CSS:ExampleLive Demo div { width: 150px; height: 200px; position: relative; background-color: #808000; animation-name: myanim; animation-duration: 2s; animation-direction: alternate-reverse; animation-iteration-count: 3; } @keyframes myanim { from {left: 100px;} to {left: 200px;} } #demo {animation-timing-function: ease-out;} ease-in-out effect
Having to create a potential large array on the stack, which usually has only little space available, isn't good. If you know the size beforehand, you can use a static array. And if you don't know the size beforehand, you will write unsafe code. Variable-length arrays can not be included natively in C++ because they'll require huge changes in the type system.An alternative to Variable-length arrays in C++ is provided in the C++ STL, the vector. You can use it like −Example#include #include using namespace std; int main() { vector vec; vec.push_back(1); vec.push_back(2); vec.push_back(3); ... Read More
Use the animation-timing-function to set the speed curve of the Animation. You can try to run the following code to set ease and ease-in animation effect:ExampleLive Demo div { width: 150px; height: 200px; position: relative; background-color: yellow; animation-name: myanim; animation-duration: 2s; animation-direction: alternate-reverse; animation-iteration-count: 3; } @keyframes myanim { from {left: 100px;} to {left: 200px;} } #demo1 {animation-timing-function: ease;} #demo2 {animation-timing-function: ease-in;} ease effect ease-in effect
Use the animation-timing-function property, with the ease value to set animation with a slow start, then fast, to end slowly with CSSExampleLive Demo div { width: 150px; height: 200px; position: relative; background-color: yellow; animation-name: myanim; animation-duration: 2s; animation-direction: alternate-reverse; animation-iteration-count: 3; } @keyframes myanim { from {left: 100px;} to {left: 200px;} } #demo1 {animation-timing-function: ease;} ease effect
The Rule of three is a rule of thumb when using C++. This is kind of a good practice rule that says that If your class needs any ofa copy constructor, an assignment operator, or a destructor, defined explicitly, then it is likely to need all three of them.Why is this? Its because, if your class requires any of the above, it is managing dynamically allocated resources and would likely be needing the other to successfully achieve that. For example, if you require an assignment operator, you would be creating copies of objects currently being copied by reference, hence allocating ... Read More
To select all elements with class=”mydemo”, you can try to run the following code. Use the .class CSS selector to achieve this,ExampleLive Demo .demo { border: 2px dashed orange; } Heading 1 Heading 1 Heading 2
The rule of five is applied in C++ for resource management. Resource management frees the client from having to worry about the lifetime of the managed object, potentially eliminating memory leaks and other problems in the C++ code. But this management comes at a cost. The Rule of The Big Five states that if you have to write one of the following functions then you have to have a policy for all of them. If we have an Object Foo then we can have a FooManager that handles the resource Foo. When implementing FooManager, you'll likely all need the following ... Read More
