Do it in Style — CSS

Thanks for setting the rules in 1994.

Motto: To break the rules, there should be rules.

CSS keeps forcing its boundaries and I am trying to follow the suit: external style sheets are my favourite playgrounds. Games include, but not limited to, PSD to HTML/CSS conversions, libraries and complete frameworks such as Bootstrap or LESS, grid systems such as 960, always using reset rules, or setting the responsive design rules manually...

Web Fonts

The users used to need to have a font locally installed to be able to correctly view it. Not anymore.

What is Parallax Effect?

Parallax scrolling is yet another technique introduced to improve user experience. The images are attached as background images via CSS codes, which are scrolled at a slower speed than that of the text on the foreground, creating the illusion. Please note that this technique is JavaScript-free.

CSS pre-processors

  1. LESS
  2. SASS
  3. Stylus
  4. PostCSS
  5. None of the above
Usage of a pre-processor might be great for development, but for production?
For more info:

Extra tools to standardise and simplify tasks, are sometimes less efficient than doing just the tasks themselves.
And adding yet another "render-blocking" file from a CDN, such as this,
<script src="//cdnjs.cloudflare.com/ajax/libs/less.js/2.7.2/less.min.js" type="text/javascript"></script>
is certainly not how the speed is improved.

How does this code simplify...


/* Mixin */
@base: #663333;
@lighter1: lighten(spin(@base, 5), 10%);
@lighter2: lighten(spin(@base, 10), 20%);
@darker1: darken(spin(@base, -5), 10%);
@darker2: darken(spin(@base, -10), 20%);

/* Implementation */
.one   {color: @base;}
.two   {color: @lighter1;}
.three {color: @lighter2;}
.four  {color: @darker1;}
.five  {color: @darker2;}

...this code?


/* Compiled CSS renders the below code */
.one   {color: #663333;}
.two   {color: #884a44;}
.three {color: #aa6355;}
.four  {color: #442225;}
.five  {color: #221114;}

However, being against the usage of a technology does not mean I cannot use it. None of these CSS pre-processors is some relativity theory and any good CSS coder can become an expert LESS coder in no time.

Native CSS variables are coming!

Please take a look at the simplicity of the below code.
For more info:

:root {
    /* declare variables */
    --darkred-background-colour: #bb0000;
    --white-font-colour: #fff;
    --width-not-to-exceed: 500px;
    --proportionate-height: calc(var(--width-not-to-exceed) / 2);
    --make-it-an-ellipse: 50%;
    --horizontal-alignment: center;
    --vertical-alignment: middle;
}

#native_CSS_variables {	
    /* use the declared variables */
    background-color: var(--darkred-background-colour);
    color: var(--white-font-colour);
    width: var(--width-not-to-exceed);
    height: var(--proportionate-height);
    border-radius: var(--make-it-an-ellipse);
    text-align: var(--horizontal-alignment);
    vertical-align: var(--vertical-alignment);
      /* oldschool css */
      display: table-cell;
      padding: 1em;
}

And the output is

I am the div with the ID of "native_CSS_variables"
