1. Map is not displayed properly

if there is an error in browser's console stating:

Google Maps API error: MissingKeyMapError

you need to create a google maps api key as described in this article:

https://developers.google.com/maps/documentation/javascript/get-api-key

Make sure you authorize the contact page url containing the map when you create the key.

then go to theme options -> map options -> google maps api key and paste it there

2. My fullscreen parallax image is not responsive and does not scale well

When the browser displays a fullscreen image will do so taking three factors in account:

- display resolution (width and height)

- display mode (portrait or landscape)

- image aspect ratio (width vs height)

So to display using the current resolution and display mode and preserving the aspect ratio, the browser will crop the image: in portrait will preserve the height whereas in landscape mode will preserve the width, cropping the rest that does not fit in current res.

The attached images visually explains the cropping process.


3. How to change the color of a Contact Form 7 placeholder text

Add this CSS code to theme options -> styling options -> custom css:

::-webkit-input-placeholder { /* WebKit browsers */
color: #000 !important;
opacity: 1;
}
:-moz-placeholder { /* Mozilla Firefox 4 to 18 */
color: #000 !important;
opacity: 1;
}
::-moz-placeholder { /* Mozilla Firefox 19+ */
color: #000 !important;
opacity: 1;
}
:-ms-input-placeholder { /* Internet Explorer 10+ */
color: #000 !important;
opacity: 1;
}

4. What should be the 'standard size' for images?

The standard we use is to have 1600px width for full-width images and 800px width for thumbnails

If you are using Adobe Photoshop, save images with 60% quality.

5. How can I add my own custom icons/fonts to the theme?

Try uploading the files somewhere as a subfolder of the theme and then use @font-face to create a font family.

And then simply add the font-family style for each element you want to have that font.

See here for a description of the process:

You can edit style.css or use customizer -> Additional CSS

6. How do I upgrade the theme? Will I lose all my changes?

To upgrade the theme:

Download the latest version from envato (installable Wordpress file)

In admin dashboard: 

remove the old theme and install the new version

using FTP remove the theme folder from /wp-content/themes/ and then copy the new version

You will not lose the changes if you added content, uploaded media or changed theme/page options.

if you haven't modified the theme files you should be fine.

7. How to optimise the speed of my website?

One of the main reasons the site is slow is that you may have lots of images which are not optimised for web.

https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/image-optimization?hl=en

To check which images slow down the site. If you go to chrome, and right click and the 'Inspect' you will see a 'Network' tab which helps you monitor the loading time for all elements.

Click on the 'time' column to sort the entries.

Second you can use one of the WordPress cache plugins to deliver cached content:

Third, compress your images  using a plugin such as WP Smush

Fourth, optimize your WordPress installation using a plugin like WP-Optimize.

Fifth, use a CDN (Content Delivery Network) to deliver your content over the web.
