Welcome to Aliascss!
AliasCSS or in short acss, is a post css processor/compiler means it lets you first define classnames in your html element then get processed to corresponig css declaration.
With aliascss you can style your webpages using class attribute with post-define classname, for example
<h1 class="color-red font-size12px display-inline-block"> Hello world</h1>OR, using shorthand
<h1 class="c-red fs12px dib"> Hello world</h1>Here we have defined the color, font size, display properties of h1 element first, then aliascss will compiles and defines the classname with the corresponing property and value/s in the styles tag or stylesheets. Generally every aliascss classname hold single propery and value for it.
npm install aliascss
<script defer src="https://cdn.jsdelivr.net/npm/aliascss/build/aliascss.js"></script>If you know CSS then your know already Aliascss. Aliascss let you to apply css directly in the html with the help of post define classname. Let's assume we need to style our h1 element
<h1>Hello World!</h1>
Normally , we will apply style as shown below
h1{
color:gray;
font-size: 18px;
}
Now , if we want same result using aliascss, then
<h1 class="c-gray fs18px">Hello World!</h1>
Or by using full semantic classname
<h1 class="color-gray font-size18px">Hello World!</h1>
Here if you look carefully the classname is doing dual responsibilty. one is defining classname and second is also defining css declaration for itself. In AliasCSS ecosystem we first use classname, then the compiler will define classname and corresponding property and value in the stylesheet/style tag. you dont have to use aliascss compiler in production.
| Aliascss classnames | Short-hand | Corresponding style aplied |
|---|---|---|
display-flex |
df |
display:flex |
list-style-none |
lsn |
list-style:none |

There are two ways to use class name, either using shorhand e.g c-red m20px df p20p30px l-30px OR full semantic class name color-red display-flex padding20px30px left-30px
We can also target psedu selector / element in your class name by using flags(-- or for shorhand -) e.g --hover or -h. For an example:-
<div class="bgc-cccccc --hover-bgc-yellow> Hi! i will change background color on hover</div>
Here by using --hover flag ( can be used -h shorthand flag) we are telling to use it in :hover state
Flags:-
| flags | short-flag | corresponding css declaration |
|---|---|---|
| --active | -a | :active |
| --after | -af | ::after |
| --after-hover | -afh | ::after:hover |
| --before | -bf | ::before |
| --before-hover | -bfh | ::before:hover |

:focus{list-style:none;} |
|
--nth-child-2n-margin-left20px |
-nc-2n-ml20px |
:nth-child(2n){margin-left:20px ;} |
Similary , we can also tell aliascss classname to use selector by using '_' at the begining class name . eg:-
<div class="_h3-c-white _p-fs14px"" >
<h3>Hello World</h3>
<p> Welcome to AliasCSS </p>
</div>\
AliasCSS will compile above classnames as below:-
....
._h3-c-white h3{
color:white ;
}
._p-fs14px p{
font-size:14px ;
}
| Aliascss Classsname | compiled |
|---|---|
_div-df |
._div-df div{..} |
__div-df |
._div-df > div{..} |
___div-df |
._div-df + div{..} |
____div-df |
._div-df ~ div{..} |
_all-c-red |
._all-c-red *{..} |
To target Device , we can simply add device prefix at the very begening of classname. for eg:-
<p class="xs-dn">This will not show in smmaler device</p>
or using semantic classname
<p class="xs-display-none">This will not show in smaller devices</p>
| AliasCSS Device Prefix | CSS Selector |
|---|---|
| @media print | |
| xs | @media (max-width : 576px) |
| sm | @media (min-width : 576px) |
| md | @media (min-width : 768px) |
| lg | @media (min-width : 992px) |
| xl | @media (min-width : 1200px) |
| hd | @media (min-width : 1408px) |
| _sm | @media (max-width : 576px) |
| _md | @media (max-width : 768px) |
| _lg | @media (max-width : 992px) |
| _xl | @media (max-width : 1200px) |
| _hd | @media (max-width : 1408px) |
Any of the above prefix can be used, these prefix must be the at the begining of the classnames. Few examples:-
Define
<div class="xs-flex-direction-column">...</div>
//using shorthand <div class="xs-fdc">...</div>
Compiled
@media (max-width : 768px) {
.mob-flex-direction-column{
flex-direction: column ;
}
}
Define
<div class="xs_p-flex-direction-column">...</div>
//using shorthand <div class="xs_p-fdc">...</div>
Compiled
@media (max-width : 576px) {
.xs_p-flex-direction-column p{
flex-direction: column ;
}
}
Define
<div class="tab-width500px">...</div>
//using shorthand <div class="tab-w500p">...</div>
Compiled
@media (min-width : 768px){
.tab-width500px{
width:500px ;
}
}
- In general every aliasCSS classnames are derived from css property and value we want to apply.i.e display-flex, color-red, wigth100px, margin-left2rem etc, similary short-hand classnames are also derived for first letter of property follwed by every first letter after '-'followed by first letter of value and evry first letter after '-' if it has any. For Example
display:flex => df or display-flex
font-weight-bold=> fwb or font-weight-bold
animation-timing-function: ease-in-out => atfeio or animation-timing-function-ease-in-out
width:100px => w100px or width100px
width:-100px => w-100px or width-100px
if there is '-' in classname before length or numeric unit it will treated as negative value. e.g w100px => width:100px , w-100px =>width:-100px , margin100px=> margin:100px, margin-100px => margin:-110px, fs-12px => font-size:-12px; fs12px=> font-size:12px; Becarefull when using '-' before numeric value.
- Repace "." with d and "%" with p, note this only appicable to numeric and length unit . "d" must be between two numeric value. i.e d5 not != .5, use 0d5 => 0.5

With npm version there are lots of exrta front-end / workflow feature we can use out of the box.
npm intstall aliascss
To Compiler folder from command line
npx aliascss 'public/*.html' 'public/css/acss.ccc'
output css file must be there if not it should be created manully.
Guide-
npx aliascsss 'glob-patterm' 'path/to/output/style.css'
npx aliascss 'public/*.html' 'public/css/acss.ccc' --watch
@package.json
....
"scripts": {
...
"aliascss-build": "aliascss 'public/*.html' 'public/css/aliascss.css'",
"aliascss-watch": "aliascss-build --watch"
}
...
.aliascss.config.js gives you more feature and power to the workflow.
@.aliascss.config.js
Basic structure of config file
export let config= {
//input files in glob pattern to get compiled
input:'public/*.html',
//Output css file , must exist or should be created manully if not exist
output:'./public/css/acss.css',
//Truncate the css file , you should let it true unless you know what your are doing
truncate:true,
custom:{
color:{
'main':"rgb(12,23,45)",// now you can use bgc-main
'theme':'#c6c6c6'
},
length:{
'1cv':'25%'
}
},
// predine classname and
extend:{
'outline-color':'color: blue',
//now you can use it with device or seduo --hover-outline-color
},
//if you want to add some css statement
statement:`

}
`,
// group classname in single classname
group:{

},
//if some of the classname collide with other CSS framework like bootstrap , tailwindcss
//You wanna tell aliasccss to ignore it...
