pictures with 100%

Hi there,

100% width of the container? That depends on where the picture is inserted.

Can you link me to the page and specify the element?

Hi Leo,

When making a new page using sections... adding a new image in a section.... the image has a padding. And is not occupying the whole width.

check this out please: http://matahum.com/sample/

at the same time, when making columns, I wanted to put a background to only half of the column i made. Example, on the second section of the sample page above, I would only want to put a background on the first column. How to do this?

For creating columns, I would recommend using Lightweight Grid Columns: https://en-ca.wordpress.org/plugins/lightweight-grid-columns/

See FAQ on that page, you can each of the columns classes, then just add the background image to that class like:

.my-column-class {
    background-image: url(URL here);
}
