using SVG on your web

SVG Scalable Vector Graphics is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. Because of its scalable native, especially with very high graphical screens(example: retinal screen for Mac) these days, we need solutions for images or graphics to be display on these screens.

Well these are many ways to resolve these, such as using large image 2x of your current size and scale down to smaller dimension on web, or for icons we use Font-icons. Since SVG was widely used on most modern browsers including IE9, and its pretty lightweight we should make use of it.
How we can use SVG on the web and why we will use it.

remove trail for css transition

While working on some css transition recently faced a small problem, the item that was animated create a trail (some white lines or cut images) where animated, that created a very experience for users, there isn’t real fix yet, however the temporary solution is to use hardware accelerated css property to improve the graphic rendering

Add this property to where you transition the css, hope this help you.

-webkit-transform: translate3d(0,0,0);

Using sourcemap for front-end development

most of the time when you are using compressor like SASS or Less, and you might find that is difficult to debug the css / javascript code, especially when you compressed the code into Compressed Version, Internet always have solution for this kind of problem, SourceMap which already supported by major browsers, Chrome and Firefox. here is a good source to read more about – <a hrefs=”https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit”>sourcemap</a>

to simplify, SourceMap allow us to live edit or debug compiled and compressed files like sass, coffeescript from the main source file. 

This is how you do on chrome, 

Open up your Developer Tools and click on settings, make sure that the option: Enable css “Enable CSS source maps” and “Auto-reload generated CSS” are both ticked.

Now you need to map your css to sass or scss file, 
Open the Source tab from developer toolbar and right click the css you want to map to the scss

Gulp js streaming build system

well if you are familiar with Grunt, this is another alternative task build tool Gulp, which is easier and flexible than Grunt

npm install -g gulp

If you are not familiar with Grunt or Gulp which both are tools that help you improve your workflow such as automated your script compiling, lint, minify it and output into another folder, every time you made an change. Its awesome tool that was built.

It just happened that I was reading some news and got into this Gulp thing and start exploring it, and found that its awesome and much easier to use than Grunt.

both are built in node, so you need to install the node module when you start an project,

at the root of your project folder, enter this in your terminal

npm install gulp —save

this will install, and now you can start creating a node script file, gulpfile.js

gulp use each plugin for each different task and thats a great concept, there are only 5 functions that you need know,

gulp.task // create a new task or action 

gulp.src // the source of this file start with same folder as gulpfile.js

gulp.run // run the task / action

gulp.watch // watch this folder or file if made some changes

gulp.dest // the destination of folder to output

Below is an example of how Gulp file work using gulp-sass plugin which will compile scss to css, if you are interested to read more, I suggest that you go directly to the gulp github repo. By the way when I install gulp using older version of Node.js I faced some problem watching the file, so you might want to update your node.js.

var sass = require(‘gulp-sass’);
var gulp = require(‘gulp’);
gulp.task(‘dosass’,function(){
gulp.src(‘sass/*.scss’).pipe(sass()).pipe(gulp.dest(‘./sass/css’));
})
gulp.task(‘default’, function() {
  gulp.run(‘dosass’);
  gulp.watch(‘sass/*.scss’, function(event){
    gulp.run(‘dosass’);
  })
})

Css filter

Recently I have been using the new CSS element called Filter alot, Its beautiful and easy to use, too bad not all browser are supporting it, infect what i know is for now is only -webkit- browser

Here are some properties that we could use:

  • blur
  • grayscale
  • drop-shadow
  • sepia
  • brightness
  • contrast
  • hue-rotate
  • invert
  • saturate
  • opacity

If you intend to try out now, just do -webkit-filter: blur(10px); // or other properties

By mixing with some of the properties you can get great effects like those Instagram right on your browser, only with CSS, thats really simple and awesome for me.

here is a link to the playground, check it out.
