Contact Form 7 - Locating Response Message Box Anywhere

After a visitor of your blog submits the contact form, the visitor sees a response message from Contact Form 7, such as “Your message was sent successfully” or “Validation errors occurred.” I sometimes hear from users who tell me that the position of the response message is not good, and, in fact, sometimes their visitors miss the message entirely.

The response message is shown at the bottom of the form by default. You can change the location by putting a response message placeholder [response] inside the form. You can insert this [response] tag into any place of your choice. You can use it multiple times in a form. The response message will be shown within the placeholder after submission.

Media Queries Tutorial - Responsive Website

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
This will take control of the layout on mobile browsers. Place this inside the tag and you’re ready to go.

-------------------------------------------------------------------------------------------------------------------------------

Working < 960 Viewport

This is our first media query that will target screens less than 960px.
/* VIEWPORT < 960px */
@media only screen and (max-width: 960px){
#container{ width: 768px; }
}
Since our layout is now less than 960px, we will style all the main container elements by changing the width to 768px.

-------------------------------------------------------------------------------------------------------------------------------

Working < 768 Viewport

The above CSS is our second media query that will target screens less than 768px (Tablet Portrait).

@media only screen and (max-width: 768px){
#container{ width: 524px; }
}
