Hi @dem10,
Please can you include the link to your site in future support requests? It makes it a little easier for us to pull up your site. Based on your previous requests, I’m taking a look at the following site:
https://www.infoliga.schleider.com.ar/
Which specific widget are you attempting to change the width for? We can help best if you point out specific parts of your site and how you’re trying to change them.
The width of the three widgets in the footer of your site is currently set with the following CSS:
.widget {
width: 100%;
}
You could use your browser’s inspector tools to find unique identifiers for each widget and then change the width for them. You can find some good guidance, including video walk throughs, for using your browser’s inspector tools in such a way:

Hope that information’s helpful.
