Home page work incorrect

Hi,
Firstly, you can find here for the document guide on how to configure the theme: http://www.designwall.com/guide/dw-focus/

About the DW Focus News Grid widget in the DW Tabs widget as the first image, you can add the following code to the Custom CSS (Dashboard > DW Focus > General setting)

.nav-tabs {
   background: #000;
}
.nav-tabs .active a, .nav-tab .active a:hover {
    position: relative; 
    color: #fff !important;
    background: #ee3224 !important;
    height: 43px !important;
}
.nav-tabs li {
   margin-bottom: 0px;
}
.nav-tabs li.active a, .nav-tabs li.active a:hover, .nav-tabs li.active a:focus {
   border: none;
}
.nav li a:hover, .nav li a:focus {
    background-color: #111;
}
.nav-tabs li a {
    border: none;
    height: 43px;
    color: #fff;
}

Then add the following code to the style.css file:

.nav-tabs .active a:before, .nav-tabs .active a:hover:before {
   border-left: 6px solid transparent;
   border-right: 6px solid transparent;
   border-top: 6px solid #EE3224;
   bottom: -6px;
   content: "";
   height: 0px;
   left: 50%;
   margin-left: -6px;
   position: absolute;
   width: 0px;
}

About second image, this issue came from the image not same height, you can use the image size 700×400 or you can add the image height in the \wp-content\themes\dw-focus\inc\init.php file. Find the line 35.
add_image_size( 'dw-focus-archive', 230, 120 );

About the content, you can use the Read more line or add the content that you want to display to the Excerpt section.
See the screenshot: http://prntscr.com/8f26ug
Note: You can setting to display content or Excerpt in the Widget.

With the third image, I have checked and I think you have resolved this issue.
If you still face any issue, please let us know.
Hope this helps !
