Use the animation-direction property to set whether an animation should be played forwards, backward or in alternate cycles.You can try to run the following code to implement the animation-direction property:ExampleLive Demo div { width: 150px; height: 200px; background-color: yellow; animation-name: myanim; animation-duration: 2s; animation-direction: reverse; } @keyframes myanim { from { background-color: green; } to { background-color: blue; } }
The uniform() function is defined in the random module of the standard Python library. It returns a random floating-point number between a given range of numbers>>> import random >>> random.uniform(10,100) 20.118467024396452 >>> random.uniform(10,100) 23.739576765885502
To set-top tooltip, use the bottom CSS property.You can try to run the following code to set-top tooltip to a text:ExampleLive Demo .mytooltip .mytext { visibility: hidden; width: 140px; background-color: blue; color: #fff; z-index: 1; bottom: 100%; left: 60%; margin-left: -90px; text-align: center; border-radius: 6px; padding: 5px 0; position: absolute; } .mytooltip { position: relative; display: inline-block; margin-top: 50px; } .mytooltip:hover .mytext { visibility: visible; } Keep mouse cursor over me My Tooltip text
The random module in the Python standard library provides a shuffle() function that returns a sequence with its elements randomly placed.>>> import random >>> l1=['aa',22,'ff',15,90,5.55] >>> random.shuffle(l1) >>> l1 [22, 15, 90, 5.55, 'ff', 'aa'] >>> random.shuffle(l1) >>> l1 ['aa', 'ff', 90, 22, 5.55, 15]
Use the transition-delay property to delay the transition effect with CSS. You can try to run the following code to set a 1 second delay of transition:ExampleLive Demo div { width: 150px; height: 150px; background: blue; transition: width 3s; transition-delay: 1s; } div:hover { width: 250px; } Heading One Hover over the below box to change its width. It begins with a delay of 1 second.
The seed() method of random module initializes the random number generator.random.seed(a,b)If a is omitted or None, the current system time is used. If randomness sources are provided by the operating system, they are used instead of the system timeIf a is an int, it is used directly.With version 2 (the default), a str, bytes, or bytearray object gets converted to an int and all of its bits are used.With version 1 (provided for reproducing random sequences from older versions of Python), the algorithm for str and bytes generates a narrower range of seeds.
To select elements, use the element selector. You can try to run the following code to select elements:ExampleLive Demo p { color: blue; background-color: orange; } Demo Website Learning Tutorials on web dev, programming, database, networking, etc. Every tutorials has lessons with illustrations and figures.
Use the transition-timing-function property to set the speed curve of the transition effect. The values you can set are ease, ease-in, ease-out, linear, etc.You can try to run the following code to set the speed curve of the transition effect with CSSExampleLive Demo div { width: 100px; height: 100px; background: red; transition: width 4s; } #effect1 { transition-timing-function: linear; } #effect2 { transition-timing-function: ease-in; } div:hover { width: 250px; } Transition Effect Hover over the div elements and see the transition effect and the speed: linear effect ease-in effect
To set right tooltip, use the left CSS property.You can try to run the following code to set right tooltip to a textExampleLive Demo .mytooltip .mytext { visibility: hidden; width: 140px; background-color: blue; color: #fff; z-index: 1; top: -6px; left: 100%; text-align: center; border-radius: 6px; padding: 5px 0; position: absolute; } .mytooltip { position: relative; display: inline-block; } .mytooltip:hover .mytext { visibility: visible; } Keep mouse cursor over me My Tooltip text
To position tooltips correctly, use the right, left, top and bottom properties.Let us see how to position tooltips on the right:ExampleLive Demo .mytooltip .mytext { visibility: hidden; width: 140px; background-color: blue; color: #fff; z-index: 1; top: -6px; left: 100%; text-align: center; border-radius: 6px; padding: 5px 0; position: absolute; } .mytooltip { position: relative; display: inline-block; } .mytooltip:hover .mytext { visibility: visible; } Keep mouse cursor over me My Tooltip text
