Front Page template doesn't work

Hi guys,
I have a site on Xampp and I’d like to use the Front Page template for multiple pages but when I selected it on the templates list, after the refresh, the page disappear. I’d like to havew a full width and no margin pages but I don’t know hoe to figured it out. I tried to select the Full Width template and modify on CSS with this code:

.page-template-page_fullwidth .content-wrapper { margin-left: 0; margin-right: 0; width: 100%; padding: 30px 15px !important; }

but nothing changed.
There’s a screenshot: https://drive.google.com/open?id=0BztOsMJEFdA3QkdleGVCVUc2WWs

Could you help me to let it works or at least explain me how to remove the margins on full width templates?

Thank you guys.

Hi there,

Please try this CSS code instead:

.page-template-page_fullwidth .site-content {
    max-width: 100%;
    padding: 30px 15px;
}

Thanks for the answer @Awan
I tried but it didn’t work. It still shows the margins.
Why I can’t use Front Page template for more pages?

I think its better if you share your site URL here, I need to check it directly.

You can still using Front page template, but you also need to use Page Builder when activate the front page template.
