[rufino]

	Hello every one,

Hello all !

I am working on the landing of my API doc. I am using apigee responsive template.

I want to set a background image in full width and I want to delete the search bar. Someone knows how to modify a template? I have tried so many things but nothing work.

Thanks in advance for your help

Here is my code :

<div class="banner" style="height: 100vh; width: : 100vw; background-image: linear-gradient(-225deg, rgba(0,101,168,0.6) 0%, rgba(0,36,61,0.6) 50%), url('http://spideo.tv/wp-content/uploads/2017/11/spideo_highline_small.jpg');">
  <div class="banner-content">
    <h1>Apidocs</h1>
    <p>Welcome to our Apidoc</p>
