海外TECH	DEV Community	Build your CSS loader with only one div — The Dots	https://dev.to/afif/build-your-css-loader-with-only-one-div-the-dots-3882	Build your CSS loader with only one div ーThe DotsYes another post about CSS loaders but this time you will build the loader In this article I will share with you a few tricks I used to build some of my loaders In case you have missed it I created a collection of single div loaders where you will find loading dots We will see the magic behind some of them There are a lot of techniques to create loading dots I will focus on my favorite one which is radial gradient and background animation Well another boring tutorial where we will have a ton of code complex keyframes and insane animation delays right No at all In this tutorial you will have ️One div️One keyframes️No delay and No complex time calculation️We will not make one animation but many of them using the same code structure️Not boring because this article will end before you even have time to blink Building the dotWe first create one dot using the following code demo link dot background radial gradient farthest side currentColor red background size px px background position top center background repeat no repeat The logic is simple I create a background layer having a size equal to x placed at the top center and I disable the repetition to have only one instance That layer is a radial gradient having two colors the currentColor which is the color you define within the color property useful to update the dot coloration later and a transparent color I am using red here to clearly see the limit of the gradient layer farthest side allow me to consider the farthest side for my percentage reference and since we are dealing with a square gradient x all the sides are the farthest one so by using currentColor I draw a circle that touch the sides no complex value like or But you are using not True and this is because gradient aren t anti aliasing so we have to consider a smaller value to have a smooth edge Below a difference between and That s all Now we have our dot so let s animate it Animating the dotTo animate the dot we simply animate the background position Let s create a keyframes that update the position from top center to bottom centerOur code will become demo link dot background radial gradient farthest side currentColor background size px px background position top center background repeat no repeat animation m s infinite alternate keyframes m to background position bottom center I think the above is self explanatoryWe can also transform the code like below It will make things easier for the next steps dot background radial gradient farthest side currentColor background size px px background repeat no repeat animation m s infinite alternate keyframes m background position top center background position bottom center Now you can animate one dot All you have to do is to update the positions to whatever you want For anyone not familiar with background position I highly recommend reading my previous article and more precisely the section talking about the percentage values Later I will consider percentage values instead of keywords like top center which is equivalent to In my previous article I am giving all the equivalence Adding more dotsTo add more dots we simply add more divs placed next to each other Then each one will have a background layer and its own keyframes animation and Of course NO To add more dot we simply add more background layers We can have as many layers as we want so one div can hold a lot of dots Let s try with demo link dot background radial gradient farthest side currentColor radial gradient farthest side currentColor background size px px background repeat no repeat animation m s infinite alternate keyframes m background position top left bottom right background position bottom left top right One dot will animate from top left to bottom left and another one from bottom right to top right As simple as that Notice that I am keeping only one background size because all my dots will have the same size Let s optimize the code using CSS variable and percentage values demo link dot d radial gradient farthest side currentColor background var d var d background size px px background repeat no repeat animation m s infinite alternate keyframes m background position background position The variable d will avoid us the repetition of the same gradient syntax For the percentage values it s more a preference that an optimization It easier for me to deal with values than keywords Did you already blink No problem because we are almost done We have all the ingredients to build any kind of loading dots Creating the loaderTo build the loader you will first need a pen amp paper Yes I am not joking People tend to jump into their favorite Code Editor and start writing code trying to imagine in their head how things should work No no it won t work that way You put everything on a paper and then you translate it into a code Step define you structureIn this step we decide about the number of dots their size the gaps etc So let s say I will be using dots having a size of x and a gap of px This will give me a total width of px I don t want them to jump a lot so let s have a height of pxStep write the codeWe translate what we defined in into a code dot width px height px d radial gradient farthest side currentColor background var d var d var d var d background size px px background repeat no repeat Don t worry about the result you get so far You will see only one dot because all of them are above each other We didn t define any background position yet Step build your timelineIn this step you need to use your imagination to define each frame of your full animation Draw a step by step illustration of the animation you have in mind Here is an example where my animation will move all the dots from the bottom to the top one by one then move them back to bottom I have frames and it s important to note that the last one is the same as the first one to have a continuous animation Step translate the timeline into background positionsNow that you have your drawing simply define the background position for each frame For each dot we have a fixed X coordinate and only the Y will change For X we have the following values Not very intuitive so let s use another syntax calc calc calc calc The logic is easy N dots so we loop from to N and we divide by N The code for our animation will be keyframes m background position calc calc calc calc background position calc calc calc calc background position calc calc calc calc background position calc calc calc calc background position calc calc calc calc background position calc calc calc calc background position calc calc calc calc background position calc calc calc calc background position calc calc calc calc It may look complex at first glance but it s very simple Inside each frame I define the position of each dot The X is always the same and I update the Y from top to bottom We have our keyframes Step find the percentage of the keyframesThe last step is to fill the with percentage values We have frames so we consider always N and we divide by to get We start for and we increment by until we reach You are done Now put everything together and enjoy The only limit to this technique is your imagination If you start playing with it you will find yourself creating a lot of fancy dot loaders You want more examples Ok let s do two more This time I will consider dots always the same sizing and the movement of each one is center gt top gt bottom gt center Notice the arrow in my drawing It means that I want an alternate animation A dots loader where I will update the X coordinate as well I think everyone got the idea Homework time Now it s your turn to build a CSS loader or even better a full collection of loaders Share your creation in the comment section I will highlight the best ones in my next article and will share them on Twitter Waiting for your CSS loaders Conclusion amp self promotionThe above is not the only technique I am using to build loading dots There are more than this but putting everything into one article will make it hard to understand If you want a follow up to this article with more tricks don t forget to You can also support me

海外TECH	DEV Community	Creating blog post images automatically for Gridsome	https://dev.to/terabytetiger/creating-blog-post-images-automatically-for-gridsome-54cl	Creating blog post images automatically for GridsomeWhen I started working on my chess side blog project I didn t want to feel the pressure of creating blog cover images for each so I started scrolling through the Gridsome Plugins and found Edmund s blog cover plugin Unfortunately for me after going through the setup process I was receiving an error message After digging through the Plugin s and Gridsome s code for an hour or two I found that the issue seemed to be occurring when Vue Remark is used in conjunction with the collection updateNode function I wasn t entirely set on using Cloudinary to host my images so I decided to modify the code so that I didn t need to programmatically update the frontmatter of my articles but rather could generate the images into a covers folder with the same name as the article thus achieving my goal of saving time with creating blog cover images npm installsIf you aren t familiar with npm check out my npm post If you are run the following npm install fs extra node html to image I m going to reference vue remark later if you want to use that you ll also need npm install gridsome vue remark Vue Remark plugin configThe important part of the configuration for generating blog cover images is the typeName for more details on configuring vue remark see the plugin s page module exports siteName Your Site Name Here plugins use gridsome vue remark options typeName Post lt Note this value baseDir content posts pathPrefix post template src templates Post vue You ll also want to make sure you have at least one markdown file created in the content posts directory with the bare minimum frontmatter intro md title Intro Postcover image covers intro png This is a sample post If you re trying to follow along make sure to create a Post vue file in your templates folder so that gridsome develop can create your post pages properly HTML to an imageSo now we ve got our sample post ready to go let s setup our html to be converted to an image In the root directory create a functions folder with a generateHtml js file inside The HTML returned by this code is going to be what becomes our post cover image This creates a basic solid background with title and a white border module exports function title backgroundColors imgHeight imgWidth border domain const bgColor backgroundColors Math floor Math random backgroundColors length const template lt html gt lt head gt lt style gt box sizing border box padding margin body min width imgWidth min height imgHeight padding px background bgColor color ffffff font family apple system system ui BlinkMacSystemFont Segoe UI Roboto Helvetica Neue Arial sans serif div container border px solid ffffff text align left padding px width height display flex flex direction column justify content space around h title font size rem text transform capitalize text align center lt style gt lt head gt lt body gt lt div class container gt lt h class title gt title lt h gt lt div gt lt body gt lt html gt return template gridsome server SetupFinally our gridsome server setup this is where we will check each time gridsome develop or gridsome build is run to see if any posts are missing a cover image If they are the image will be generated in the covers folder const fs require fs extra const createImage require node html to image const generateHtml require functions generateHtml const defaultOptions typeName Post This should be the typeName noted above Each background will randomly have one of these colors backgroundColors B df imgWidth px The width of your cover image imgHeight px The height of your cover image border true I hard coded this to true in my html domain Your domain goes here Edmund includes this in their generated images outputDir content covers Where the cover images should be generated to module exports function api Keeping this for easy modifications from gridsome plugin blog cover const options defaultOptions api loadSource async actions gt const collection actions getCollection options typeName collection data forEach function node if node internal typeName options typeName Using the same filename as the file for easy frontmatter const imgName node fileInfo name fs ensureDirSync options outputDir const output options outputDir imgName png Only generate images for files that don t exist already console log Generating Missing Cover Images fs access output error gt if error console log Creating imgName png createImage output html generateHtml node title node subtitle options else console log output already exists if updateNode worked this is where it would go Thanks again to Edmund for the baseline work for this	2021-09-15 14:31:08
