Use the CSS Transform Property skewY to Skew an Element Along the Y-Axis Given that the skewX() function skews the selected element along the X-axis by a given degree, it is no surprise that the skewY() property skews an element along the Y (vertical) axis. Skew the element with the id of top -10 degrees along the Y-axis by using the transform property.
Use the CSS Transform Property skewX to Skew an Element Along the X-Axis The next function of the transform property is skewX(), which skews the selected element along its X (horizontal) axis by a given degree. The following code skews the paragraph element by -32 degrees along the X-axis. p { transform: skewX(-32deg); } Skew the element with the id of bottom by 24 degrees along the X-axis by us..
Use the CSS Transform scale Property to Scale an Element on Hover The transform property has a variety of functions that let you scale, move, rotate, skew, etc., your elements. When used with pseudo-classes such as :hover that specify a certain state of an element, the transform property can easily add interactivity to your elements. Here's an example to scale the paragraph elements to 2.1 times..
Use the CSS Transform scale Property to Change the Size of an Element To change the scale of an element, CSS has the transform property, along with its scale() function. The following code example doubles the size of all the paragraph elements on the page: p { transform: scale(2); } Increase the size of the element with the id of ball2 to 1.5 times its original size.
Create Texture by Adding a Subtle Pattern as a Background Image One way to add texture and interest to a background and have it stand out more is to add a subtle pattern. The key is balance, as you don't want the background to stand out too much, and take away from the foreground. The background property supports the url() function in order to link to an image of the chosen texture or pattern. T..
Use a CSS Linear Gradient to Create a Striped Element The repeating-linear-gradient() function is very similar to linear-gradient() with the major difference that it repeats the specified gradient pattern. repeating-linear-gradient() accepts a variety of values, but for simplicity, you'll work with an angle value and color stop values in this challenge. The angle value is the direction of the gr..
미디어 쿼리를 사용하여 변수 변경하기 CSS 변수는 미디어 쿼리를 사용하는 방식을 단순화할 수 있습니다. 예를 들어, 화면이 미디어 쿼리 중단점보다 작거나 클 때 변수의 값을 변경할 수 있으며 사용되는 모든 위치에 스타일이 적용됩니다. 미디어 쿼리의 :root 선택기에서 --penguin-size가 재정의되고 200px 값이 지정되도록 변경합니다. 또한 --penguin-skin을 재정의하고 검은색 값을 지정합니다. 그런 다음 미리 보기의 크기를 조정하여 이 변경 사항이 실제로 적용되는지 확인합니다.
Change a variable for a specific area When you create your variables in :root they will set the value of that variable for the whole page. You can then over-write these variables by setting them again within a specific element. Change the value of --penguin-belly to white in the penguin class.
Inherit CSS Variables When you create a variable, it is available for you to use inside the selector in which you create it. It also is available in any of that selector's descendants. This happens because CSS variables are inherited, just like ordinary properties. To make use of inheritance, CSS variables are often defined in the :root element. :root is a pseudo-class selector that matches the ..
Create a custom CSS Variable To create a CSS variable, you just need to give it a name with two hyphens in front of it and assign it a value like this: --penguin-skin: gray; This will create a variable named --penguin-skin and assign it the value of gray. Now you can use that variable elsewhere in your CSS to change the value of other elements to gray. TEST In the penguin class, create a variabl..

And it's difficult to remember hex code. Fortunately, you can shorten it. For example, red's hex code #FF0000 can be shortened to #F00. This shortened form gives one digit for red, one digit for gree..
https://www.freecodecamp.org/learn/responsive-web-design/basic-css/use-hex-code-to-mix-colors Use Hex Code to Mix Colors To review, hex codes use 6 hexadecimal digits to represent colors, two each for red (R), green (G), and blue (B) components. From these three pure colors (red, green, and blue), we can vary the amounts of each to create over 16 million other colors! For example, orange is pure..

One of these ways is called hexadecimal code, or hex code for short. We usually use decimals, or base 10 numbers, which use the symbols 0 to 9 for each digit. Hexadecimals (or hex) are base 16 numbers. T..

Improve Compatibility with Browser Fallbacks When working with CSS you will likely run into browser compatibility issues at some point. This is why it's important to provide browser fallbacks to avoid potential problems. When your browser parses the CSS of a webpage, it ignores any properties that it doesn't recognize or support. For example, if you use a CSS variable to assign a background colo..
Attach a Fallback value to a CSS Variable When using your variable as a CSS property value, you can attach a fallback value that your browser will revert to if the given variable is invalid. Note: This fallback is not used to increase browser compatibility, and it will not work on IE browsers. Rather, it is used so that the browser has a color to display if it cannot find your variable. Here's h..
