Grid Style Sheets Conditional if/else Styles Example

GSS:

Grid Style Sheet, it is a modernized implementation of CCSS [Constraint CSS (CCSS)]. Today we are going to see how we can implement the conditional if/else statements inside the grid style sheet.

Nowadays responsive pages are designed by bootstrap and other stuff’s. But making the web pages responsive purely with grid style sheet is a really nice news for all the style sheet


developers. But still we may not able to achieve the full functionality due to lack of knowledge about GSS. If they provide more examples it will help all the developers to understand and implement in their development works.

 

Requirement:

GSS JS  [or]

GSS Min JS

 

GSS 2.0

 

Importing Grid Style sheet:

To import the Grid style sheet,


<link rel="stylesheet/gss" type="text/gss" href="my-awesome-styles.gss"></link>

To write in inline,


<style type="text/gss">

/* Your GSS */

</style>

Note: type is text/gss not text/css.

There are lot of things can be achieved using grid style sheet. Complete GSS guide.

 

if/else statements inside style sheets[GSS] [looks something interesting ?]

 

We are going to develop a simple responsive page using if/else gss styles. If the device is desktops/laptops then one view and if the device is mobile/tablet then one view [called responsive] is the core part we are going to achieve today only with GSS.

 

GSS Source Code:

code explanations are shared in the below source code itself.

<script type="text/javascript">

<style type="text/gss">
#author[left] == section[left];
section {

height: == ::window[height];
center: == ::window[center];

@if &[width] <= 400 {
article {
// ^[top] - top of the body when the width is less than 400 [eg:mobile devices]
// here top of the section, since this styles are inside the section tag
:first[top] == ^[top];
bottom: == :next[top];
left: == ^[left];
// -10 will reduce the width by 10 only in mobile devices view
width: == ^[width]-10;
height: == ^[height] / 2;

}
}
@else {
article {
// ^[width] -- width of the body / width of the body container [eg: container class inside body]
// here width of the section, since this styles are inside the section tag
width: == ^[width] / 2;
// ^[height] -- height of the body / height of the body container [eg: container class inside body]
// here height of the section, since this styles are inside the section tag
height: == ^[height];
top: == :next[top];
right: == :next[left];
}
