海外TECH	DEV Community	CSS nth- Selectors Variable	https://dev.to/daviddalbusco/css-nth-selectors-variable-86f	CSS nth Selectors VariablePhoto by Mario Gogh on UnsplashUsing CSS variables at least when I m writing these lines in June is not supported in media queries or selector e g nth child var my variable does not work This is a bit unfortunate but not unsolvable In some recent development I bypassed this limitation by injecting style elements in the DOM into my Web Components in order to animate block of codes in DeckDeckGo IntroductionStricto sensu the following trick is not reserve to Web Components and probably works with any elements too I just only used it so far with such technology I will first display the idea with the help a vanilla component and end the article with the same approach but implemented with a StencilJS functional component Goal Of The TutorialWe are going to develop a Web Component which renders a lt ul gt list and which can animate the display of its entries No semantic elements are going to be added or removed from the DOM once the component is load The animation will happen by modifying the style more precisely by applying a different style on the selected li nth child n Vanilla JSTo display the idea without anything else than the web we create an index html page It consumes the Vanilla component we are about to develop We also add a button to triggers the animation lt html gt lt head gt lt script type module src my component js gt lt script gt lt head gt lt body gt lt my component gt lt my component gt lt button gt Next lt button gt lt script gt document querySelector button addEventListener click gt document querySelector my component next lt script gt lt body gt lt html gt In a separate file called my component js we create the Web Component At this point without any animation We declare it open to be able to access the shadow DOM through shadowRoot we create a style to hide all li and define the transition Finally we add the ul list and its children li class MyComponent extends HTMLElement constructor super this attachShadow mode open const style this initStyle const ul this initElement this shadowRoot appendChild style this shadowRoot appendChild ul connectedCallback this className hydrated next TODO in next chapter initStyle const style document createElement style style innerHTML host display block li opacity transition opacity s ease out return style initElement const ul document createElement ul const li document createElement li li innerHTML Spine const li document createElement li li innerHTML Cowboy const li document createElement li li innerHTML Shelving ul append li li li return ul customElements define my component MyComponent At this point if we open our example in a browser npx serve we should find a component with a hidden content and a button which has no effect yet Not much to see but that s a start To develop the animation we have to keep track of the displayed li that s why we add a state index to the component class MyComponent extends HTMLElement index constructor Thanks to it we can implement the next method the one called from the button we added earlier in the HTML page Not my most beautiful code ever Let s agree it has only a demo purpose next this index this index this index const selector li nth child this index opacity let style this shadowRoot querySelector style animation if style style innerHTML selector return style document createElement style style setAttribute id animation style innerHTML selector this shadowRoot appendChild style What s happening there It first set the next index li to be displayed and create a CSS selector to apply the opacity styling In short this replaces the CSS variable we cannot use Afterwards we check if the shadowed content of our Web Component already contains a dedicated style to apply the animation If it does we update the style with the new value ーselector and if not we create a new style tag Each time this method is call a new style is applied and therefore another li nth child n is displayed If we open again our browser to give it a try items should be animated among click on our button next and if we go further and observe the component in the inspector we should notice that the shadowed style element change on each method call StencilJSLet s double the fun with the same example but using a StencilJS functional component You can start a new project with the command line npm init stencilBecause we are developing the exact same component we can copy the previous HTML content declaring the component and adding a button in the src index html of the project with an only slight small difference the method next has to be declared and called with async ーawait This is a requirement ーbest practice of Stencil public method of components have to be async lt DOCTYPE html gt lt html dir ltr lang en gt lt head gt lt meta charset utf gt lt meta name viewport content width device width initial scale minimum scale maximum scale gt lt title gt Stencil Component Starter lt title gt lt script type module src build demo stencil esm js gt lt script gt lt script nomodule src build demo stencil js gt lt script gt lt head gt lt body gt lt Same code as in previous chapter gt lt my component gt lt my component gt lt button gt Next lt button gt lt script gt document querySelector button addEventListener click async gt await document querySelector my component next lt script gt lt Same code as in previous chapter gt lt body gt lt html gt We can also repeat previous steps and create first a component which does nothing else than rendering a ul list and hidden items li import Component h from stencil core Component tag my component styles host display block li opacity transition opacity s ease out shadow true export class MyComponent render return lt ul gt lt li gt Spine lt li gt lt li gt Cowboy lt li gt lt li gt Shelving lt li gt lt ul gt By testing the component npm run start we should get the same result too To keep track of the li to highlight we need a state and the function state We add both to our component State private index number Method async next this index this index this index In comparison to the Vanilla component because we are using a bundler which simplify the development we do not have to take care of re rendering by our selves Each modification of the state will trigger a re render which ultimately update the nodes which have to be updated and only those who have to be updated Still we do have to implement the CSS selector variable For such purpose as briefly mentioned we are going to use a functional component It might work with a class component but I feel like a functional one is well suited for the job const Animate FunctionalComponent lt index number gt index gt return lt style gt li nth child index opacity lt style gt This component renders a style element for the value we path as parameter our state Finally we have to use the functional component and bind it to our state value Doing so it will be re rendered each time its value changes render return lt Host gt lt Animate index this index gt lt Animate gt lt ul gt lt li gt Spine lt li gt lt li gt Cowboy lt li gt lt li gt Shelving lt li gt lt ul gt lt Host gt That s already it we were able to replicate the same component The above component in a single block of code import Component FunctionalComponent h Host Method State from stencil core const Animate FunctionalComponent lt index number gt index gt return lt style gt li nth child index opacity lt style gt Component tag my component styles host display block li opacity transition opacity s ease out shadow true export class MyComponent State private index number Method async next this index this index this index render return lt Host gt lt Animate index this index gt lt Animate gt lt ul gt lt li gt Spine lt li gt lt li gt Cowboy lt li gt lt li gt Shelving lt li gt lt ul gt lt Host gt SummaryI am honestly not sure that this article will ever find its audience nor do I think it may be useful to someone some day but well I love to use that trick In addition it was fun to develop for demo purpose the same piece of code with Vanilla JS or Stencil To infinity and beyond DavidYou can reach me on Twitter or my website Give a try to DeckDeckGo for your next presentations	2021-06-09

海外TECH	DEV Community	Should You Really be Coding in Dark Mode?	https://dev.to/codesphere/should-you-really-be-coding-in-dark-mode-4ng8	Should You Really be Coding in Dark Mode There are few debates as contentious in the development and UX world as color schemes Among developers however there seems to be a pretty significant skew towards coding in a light on dark mode This poll found that ⅔of surveyed developers prefer to use a dark mode in their code editor Dark mode advocates cite a number of benefits including reduced eye strain better sleep and reduced power consumption While many of the arguments for dark mode undoubtedly have merit there is far from a scientific consensus on many of its benefits A Little Bit of HistoryWhile we might think of dark mode as a relatively new trend it was actually the original color scheme that was used for computers Most early computers used light text on dark background in order to save power As computers became more consumer friendly however developers began to use black text on white backgrounds to imitate the black ink on white paper that most people were used to More recently countless devices websites and apps have added support for dark mode for both optical and aesthetic reasons Software developers who spend most of their work time staring at computer screens have been some of the most fervent advocates for dark mode Eye Strain and ReadabilityThe first argument for dark mode that s worth taking a look at the claim that dark mode is better for your eyes While there is no doubt that using light mode in a dark room can be blinding there also seems to be evidence that our brains are just better at reading and comprehending black text on a white screen For example A study by Psychologist Dr Cosima Piepenbrock looked at how adults with normal vision performed at visual acuity and proofreading text across dark and light color schemes The study found that Pupil sizes were smaller and proofreading performance was better with positive Dark on Light than with negative Light on Dark polarity displays In other words for substantial digital tasks where you are attentively reading text Such as coding having dark text on a light background i e light mode can help you focus and comprehend better What this means in practice is that your eyes and brain may have to work harder to read and write code if your IDE is in dark mode Blue Light and SleepAnother commonly cited claim is that using your IDE in dark mode reduces blue light consumption and therefore can help you sleep While dark mode definitely does reduce blue light blue light may not be the primary culprit that actually messes up your sleep schedule A study by the University of Manchester found that blocking blue light only slightly improved people s sleep patterns Instead the real culprit is the use of warmer colors Like reds and yellows at night which trick our brain into thinking it s daytime If you want to get better sleep dark mode may in fact help but the real solution is to not use screens altogether before going to bed Power ConsumptionAnother argument for using dark mode in your IDE is that it can save you money on your power bill If you are using an OLED display which most modern monitors do then this is definitely true It is probably important to note however that if you are developing software that is computationally heavy like rendering D graphics or training and using machine learning models the reduced power consumption from dark mode probably won t make any sort of noticeable dent in your power bill AccessibilityRegardless of what you personally prefer while you code you should always add support for both dark and light modes in the software that you build Many people who have certain color blindness or eye conditions can find one of these themes extremely hard or even impossible to use Giving your users flexibility is therefore very important ConclusionIn summation the jury is still out on whether dark mode is actually better for coding While it might save you a tiny amount of power and if you are using it at night marginally help your sleep schedule these benefits don t seem to be that substantial In addition reading dark text on a light background may help you read and write code more efficiently Your theme therefore should come down to what is best for you because there is not a scientific consensus that one color scheme is going to be better than the other If you think dark mode looks sleeker and you are doing a lot of coding at night or in the dark then go ahead and use dark mode If you prefer the readability of dark text on a light background then go ahead and use light mode So what do you prefer and why Personally I think dark mode is more aesthetically pleasing but I definitely notice how it can be harder to read Let us know in the comments what you think	2021-06-09 14:16:51
