海外TECH	DEV Community	SASS - An Overview	https://dev.to/eunit/sass-an-overview-a4n	SASS An OverviewOverview Of SCSS SASSIn this tutorial we shall briefly take an overview of what SASS is and how to get it up and running in your localmachine so you can start using it in your projects We all get a little frustrated overwhelmed when styling large scale applications especially using plain CSS Things do get very messy easily Things can get a lot easier using SASS D Before delving in let s start with what SASS actually means SASS MeaningSASS stands for Syntactically Awesome Stylesheets It is a CSS superset which gives you programming type features andpre compiles into CSS It is essentially a CSS pre processor an upgrade to what CSS is and what CSS offers So itmakes it easier to work with CSS it reduces the repetition and saves time which ultimately leads to you styling yourpages efficiently with fewer CSS lines PrerequisiteBefore using or learning SASS you should be conversant with HTML fundamentals CSS properties Basic understanding of programming if else loops Under the hood SASSSASS works like our regular CSS but the browser does not understand SASS that is why we will need a SASSpre processor to convert SASS code into CSS Setting up SASSBefore you can use SASS you need to set it up on your project There are basically many ways to set SASS up From theSASS official documentation you can install SASS using two methods Theseare either downloading and installing different applications that will get you up and running with SASS in a few minutes for Mac Windows and Linux You can download most of the applications for free but a few of them are paid apps and totally worth it or using the command line to install SASS This will enable you to run the SASS executable to compile sass and scss files to css files For example sass source stylesheets index scss build stylesheets index css Another straight forward way of using SASS is install an extension in VSCode a text editor For you to use thismethod it means that you must be using VSCode as your text editor Thi extension is called “Live SASS Compiler itdoes all the job for you you just need to install it from your VsCode and you are good to go After successful installation a button “Watch SASS will show up at the bottom of your editor just click on itthen it will start compiling your SCSS to regular CSS One thing you should make sure to do is that you link your Scssfile with HTML but you need to link it the way you do with CSS if your SASS file name will be “style and it is placedin a folder named “SCSS then you have to link it like this lt link rel stylesheet href scss style css gt After linking it Now you can compile your SCSS file SASS just by clicking the “Watch SASS button like this SASS featuresAs we have discussed earlier in the introductory part of this tutorial SASS gives you superpowers to use over your regular CSS Below are the some of the features we can use to give us that superpowers VariablesYou can use the variables feature in SASS to avoid writing and modifying repetitive style properties Variables are useful when you want to preserve say a brand color consistent in the website Let s say we have a brand color of ffYou can declare a variable in the following manner brand color ffWhen the SASS is processed it takes the variables we defined for the brand color and outputs normal CSS with our variable values placed in the CSS This can be extremely powerful in keeping the colors consistent throughout the site SCSS file brand color ff body font font stack color brand color This will translate to our CSS as CSS file body font Helvetica sans serif color ff NestingWhen writing HTML you know that it is nested that is there is a visual hierarchy CSS on the other hand doesn t have this visual hierarchy SASS will let you nest your CSS selectors in a way that follows the same visual hierarchy of your HTML Be aware that overly nested rules will result in over qualified CSS that could prove hard to maintain and is generally considered bad practice according to theSASS official documentation With that in mind here s an example of some typical styles for a site s navigation SCSS file nav ul margin padding list style none li display inline block a display block padding px px text decoration none CSS file nav ul margin padding list style none nav li display inline block nav a display block padding px px text decoration none PartialsYou can create partial SASS files that contain little snippets of CSS that you can include in other SASS files This is a great way to modularize your CSS just like in JAvaScript and help keep things easier to maintain A partial is a SASS file named with a leading underscore You might name it something like partial scss The underscore lets SASS know that the file is only a partial file and that it should not be generated into a CSS file SASS partials are used with the import rule SCSS file import variables brand color ff background color fff body color brand color background color background color box sizing border box padding margin Note We neither added the extension scss or the underscore But beware of not having two separate files of the same name one with underscore and another without underscore It is a good practice to save all your partials in a separate folder to avoid confusion MixinsMixins are very useful to declare reusable styles for your application Some things in CSS are a bit tedious to write especially with CSS and the many vendor prefixes that exist A mixin lets you make groups of CSS declarations that you want to reuse throughout your site It helps keep your Sass very DRY You can even pass in values to make your mixin more flexible Here s an example for theme SCSS file mixin theme theme DarkGray background theme box shadow px rgba theme color fff info include theme alert include theme theme DarkRed success include theme theme DarkGreen CSS file info background DarkGray box shadow px rgba color fff alert background DarkRed box shadow px rgba color fff success background DarkGreen box shadow px rgba color fff Inheritance in SASS or the Extends keywordYou can inherit or extend the properties of any class or other selectors using the extends keyword in SASS SCSS file general container width max width px article container extend general container font size px In the above snippet we defined some styles in our general container class and using the extends keyword we will be able to use the same styles in our article container When compiled he above code will result in the following CSS styles general container article container width max width px article container font size px Seems like magic D PSASS Built in functionsSASS has many built in functions we will just review a few of them For loops and Each loops You can use loops in SASS to write repetitive styles used in your applications like CSS file col width col width col width col width This above snippet can be converted to the following code using the SASS for loop feature SCSS file for width from through col width width width Here width is the value of each iteration Notice the use of the iterating value in the class name variable ーyou can use this syntax anywhere in your SASS code to combine variables with other strings Each loops in SASS can be used to iterate through Lists Lists in SASS are basically arrays of some values We can have a list of strings names and traverse the same The syntax of each loop is little different from for loop It starts with each keyword and used in instead of through Thanks for making it to the end of this article I have included some links at the end of this post for your reading pleasure Continue Reading Sass Basics Install SASS SASS

海外TECH	DEV Community	HTML - Let's Talk About Semantics	https://dev.to/alserembani/html-lets-talk-about-semantics-4jo4	HTML Let x s Talk About SemanticsSalam and hello folks Today let s discuss semantics So what s about it SemanticsSo what is the dictionary meaning of semantics Semantics is the study of meaning reference or truth Then how about in the computer science field Semantics is the field concerned with the rigorous mathematical study of the meaning of programming languages So put it easy semantics is a way to understand easily what programming syntax means so your code will be easily read or the right word is more verbose Is it just about you able to read the code Let s proceed with the discussion The screen readersTechnology in general and specifically the web is not just about doing the products but beyond that Delivering a quality web means that more and more audiences can benefit from it whether they are visually challenged or not or anything that makes the experience of visiting the web difficult At least that is one of definitions that I come up with throughout my years though it is still little compared to other lions in the web development industry To assist these kinds of difficulties semantics are some aspects that should be highlighted so screen readers can recognise each element inside your HTML and people that require accessibilities can benefit from it CrawlersOther than that there is an entity that will crawl through your page and see what your page features Other than all your Meta tags oooops I mean meta tags crawlers will crawl through your DOM and see what is inside your content and try to classify based on the content That is why semantics is important if you really prioritise your Search Engine Optimisation SEO so crawlers can keep their eyes on your pages and serve them to the deserving audience VerbosityAnd of course for developer experience verbosity is one of the scoring points so your page can be easily maintained Providing the elements gives a contextual meaning the readers whether the technical or non technical ones can distinguish which part of your code needs to pay attention to when the time comes Okay so my point is semantics is quite important for these aspects AccessibilityVerbositySEOMaybe there are a lot more reasons for semantics so put in the comments below what you think about semantics So onto the HTML Semantics in HTMLSo what about semantics in HTML All the elements in HTML do give meaning to what you want to put inside it whether it contains navigations or information or maybe emphasising the content It s up to you of course but improving your HTML elements does give a lot of benefit to the audience and the robot Let s dive in Text lt p gt Hello DEVto lt p gt As simple as paragraph element lt p gt displaying text to the user So to tell that the tag is a title you may use class or style to indicate that is the title sure Let s do just that lt p class title gt Hello DEVto lt p gt Is this a good practice Well it is subjective whether it is right or wrong but to help screen readers and crawlers to understand your content you can use several other tags that can assist you there and improve the styling using those tags Headings title gt lt h gt lt h gt lt h gt lt h gt lt h gt lt h gt Text highlights gt lt strong gt lt em gt lt small gt lt sub gt lt sup gt lt abbr gt lt code gt Text formatting only gt lt b gt lt i gt You can actually wrap your text without any of these tags but I would not recommend that practice because screen readers won t know what those text contexts refer to Not recommended lt div gt Hello DEVto lt div gt Instead lt div gt lt p gt Hello DEVto lt p gt lt div gt Containers lt div gt lt p gt Hello DEVto lt p gt lt div gt I have seen a lot of pages that use div elements and that is okay Of course div is a way to containerise your content but oftentimes I see the div element is abused especially used for button Not exactly abused but it is better to give it meaningful context For example for navigation you can use the nav element You can put all your navigation content inside nav so your crawlers understand that the division represents your page navigation or any navigation context you intend to Navigation gt lt nav gt Layouts gt lt main gt lt section gt lt article gt lt header gt lt footer gt Contexts gt lt mark gt lt figure gt lt figcaption gt lt summary gt lt details gt lt aside gt lt address gt FormsMost of the websites nowadays required input from users whether for newsletters or registration or login or the exact thing I did so this article can be read by you Usually for simple single input I can just put lt input gt But for more than two inputs I will use lt form gt for the purpose lt form gt For simple input gt lt input gt For more diverse options gt lt select gt lt option gt lt textarea gt lt meter gt lt datalist gt For labeling gt lt label gt lt legend gt lt progress gt For actions gt lt button gt lt form gt But heed my advice NEVER USE DIV FOR BUTTONS for screen won t detect it for keyboard users This is what I am talking about regarding people abusing lt div gt for buttons Other existing semantic elementsWell of course there are other elements that already have contexts within lt table gt lt thead gt lt th gt lt tbody gt lt tr gt lt td gt lt ul gt and lt ol gt for list lt dl gt for more advanced listWell there are actually a rough total of semantic elements you can use to give more meaning of course Is semantic a must Well I wouldn t say you have to but try to improve your content so others can benefit from it and might as well help you in future for your page discovery The reason behind my writing today is about encouraging web developers to pay attention to semantics You might be thinking There are a lot of tags that I have to know then Well HTML elements are interchangeable which means that changing from div to main doesn t break any of your page content as long as you know which context it belongs to so improvisation can even come later given if you still have the motivation to go to your code and replace it My personal approachOftentimes you want to make your design system first before creating your content You can standardise your content globally using these semantic tags For example in my CSS sheet h font size rem h font size rem h h h font weight padding rem px rem section padding rem rem And then later you want to develop more complex components so then you will utilise class lt section class blog card gt blog card border radius px Or with Tailwind utilities blog card apply bg blue With these your design system will be organised standardised and easy to debug later on Well it is up to the developer in which they prefer What next after semantics If you are into semantics you might be interested in ARIA standards in HTML where it really boost experience in screen reading and accessibility Well what is your opinion in semantics Write what you think below and keep the discussion healthy A meme or two should be okay for a little bit fun but keep it in context That s it for this week And for that have some rest and peace be upon ya	2021-10-30 20:08:30
