Different number of columns based on device - html

Question

I'm trying to create different number of columns based on the device.
For example: on mobile I want 2-col layout and on desktop 4-col layout etc...
I've tried messing around with minmax() , but couldn't make it happen the way I want, any advice for achieving this with minmax().
would someone have the answer?
.wrapper {
display: grid;
grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
}
<div class="wrapper">
<div class="col">1</div>
<div class="col">2</div>
<div class="col">3</div>
<div class="col">4</div>
<div class="col">5</div>
<div class="col">6</div>
</div>

Answer 1

Not sure how you want to layout your Grid regardless you will have to use Media Queries and define each of your columns.
Example:
div class="col one">1</div>
div class="col two">2</div>
This is the mobile lay out
.wrapper {
display: grid;
grid-gap: 1em;
grid-template-areas:
"header"
"sidebar"
"content"
"sidebar2"
"footer"
}
This is the Tablet lay out
#media only screen and (min-width: 500px) {
.wrapper {
grid-template-columns: 20% auto;
grid-template-areas:
"header header"
"sidebar content"
"sidebar2 sidebar2"
"footer footer";
}
}
This is the desktop lay out
#media only screen and (min-width: 600px) {
.wrapper {
grid-gap: 20px;
grid-template-columns: 120px auto 120px;
grid-template-areas:
"header header header"
"sidebar content sidebar2"
"footer footer footer";
max-width: 600px;
}
}
Here is an example of using css grid with Media Queries. In this example, box is followed with a unique div class name. You can use that class name to layout the grid.
body {
margin: 40px;
}
.sidebar {
grid-area: sidebar;
}
.sidebar2 {
grid-area: sidebar2;
}
.content {
grid-area: content;
}
.header {
grid-area: header;
}
.footer {
grid-area: footer;
}
.wrapper {
background-color: #fff;
color: #444;
}
.wrapper {
display: grid;
grid-gap: 1em;
grid-template-areas:
"header"
"sidebar"
"content"
"sidebar2"
"footer"
}
#media only screen and (min-width: 500px) {
.wrapper {
grid-template-columns: 20% auto;
grid-template-areas:
"header header"
"sidebar content"
"sidebar2 sidebar2"
"footer footer";
}
}
#media only screen and (min-width: 600px) {
.wrapper {
grid-gap: 20px;
grid-template-columns: 120px auto 120px;
grid-template-areas:
"header header header"
"sidebar content sidebar2"
"footer footer footer";
max-width: 600px;
}
}
.box {
background-color: #444;
color: #fff;
border-radius: 5px;
padding: 10px;
font-size: 150%;
}
.header,
.footer {
background-color: #999;
}
.sidebar2 {
background-color: #ccc;
color: #444;
}
<div class="wrapper">
<div class="box header">Header</div>
<div class="box sidebar">Sidebar</div>
<div class="box sidebar2">Sidebar 2</div>
<div class="box content">Content
<br /> More content than we had before so this column is now quite tall.</div>
<div class="box footer">Footer</div>
</div>

Answer 2

I would use bootstrap
basic idea is
lg is used for large windows (desktop)
md is used for medium windows (desktop)
xm is used for small windows (i.e phone / tablets)
xs is used for extra small windows (i.e phone)
you can also hide any of these layouts
<div id="container">
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">1</div>
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">2</div>
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">3</div>
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">4</div>
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">5</div>
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">6</div>
</div>
