How to get a wider column for text (article as well as pages)

In theory what should work is adding a css-clause, either to your child theme’s styles.css (if you have a child theme) or to the customizations css like this:

.col-md-9{
width: 75%;
}
.col-md-3{
width: 25%;
}

The value you specify should be greater than 75% for the .col-md-9 class, as this is the current standard value. Adding the width for .col-md-9 and .col-md-3 should give you 100%. So if you change the first to 80% you need to change the second to 20%, if you changed the first to 90% you would need the second to be at 10% (which seriously might not be wide enough for the widgets at all – not everybody has a 40″ screen ?? )

Good luck

Hi Lille,
thanks your message, but it did not work properly.
On another WP Forum, it was proposed here after CSS code

@media (min-width: 1200px) {
.container {
width: 100%;
}
}

It works razther well

and with code we can modify width % till positive results
