Helper Classes

Text Colors

It is possible to add any color form Available Colors section by .text-[color-name] class

Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.
Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.


Similar to text colors it is possible to add backgorund color from Available Colors section by .bg-[color-name] class.

For dark background colors it is necessary to add dark class to adjust font colors and other styles. Sometimes, if inside dark element is placed element with light background you should add light class to such element.


Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.

<p class="bg-success dark p-2">Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.</p>


It is possible to add border to any of html elements by adding proper class:

  • .border - adds border to element
  • .border-top - adds top border to element
  • .border-bottom - adds bottom border to element
Element with border-bottom.
<div class="pb-10 border-bottom">Element with border-bottom.</div>

Heights & vertical center position

The template allows to set minimial height of block html element. It is possible by using .h-[value] class.
[value] is a number from 100 to 900 with 100 gap or sm (40% of viewport), md (60% of viewport) and lg (80% of viewport).

By .fullheight class you set elements height equal to the browser viewport height.

Using .v-center class makes element positioned vertically center in relation to the parent.


H2 inside 200px container.

<div class="bg-light h-200">
    <h2 class="text-center mb-0 v-center">H2 inside 200px container.</h2>

More useful helper classes are listed on Bootstrap's 4 website!


The template includes some configurable elements - here you will find informations how to use them!

Google Map

To configure Google Map it is necessary to set latitude and longitude parameters by data-latitude and data-longitude attributes of #google-map element. To get it please visit site like this.

<div id="google-map" class="h-400" data-latitude="40.758895" data-longitude="-73.985131" data-style="dream"></div>

Map supports few color themes - to set it please use data-style attribute.

Available Themes
  • wy
  • apple

Contact Form

To configure contact form please open contact-form.php file from /assets/php directory and go the line with an e-mail address to change it to your own - like this.

$emailTo = '';

After that you will recieve the messages from your websites to this e-mail address.

SentMail function must be enabled on your hositng. Otherway I recommend use and configure plugin like "PHPMailer".

SignUp Form

SignUp form is made with Mailchimp API.

How to create the form?

To create Sign Up form you have to have an account on Mailchimp site.
  1. Log into the Mailchimp site.
  2. Create subscribers list.
  3. Get into the list and go to "Signup forms" tab.
  4. Pick "Embedded forms".
  5. Pick "Classic version" and copy / paste somewhere generated code (don't change anything).
  6. Find form selector and copy action atribute valuse into your form. Remember to add method="POST" attribute.
  7. Modify action URI by changing .../post?... to .../post-json?.... It should look like this action="//"
  8. Find email input and copy type, name and id to your input - it should look like this: <input type="email" value="" name="EMAIL" class="form-control input-lg" id="mce-EMAIL">
  9. Find input which prevents bot signups and paste it somewhere in the form - it should be hidden!
  10. Add submit button and enjoy your working Sign Up form!

Local Scroll

If you want to use local scroll somewhere in the content please add data-local-scroll attribute in the parent selector of a link to local selector.


The template allows to add really cool animations for each of html elements. Let's check how to use it!

Entrance animation

This animation fires when element appears in the browser viewport. To add such animation you need to place .animated class in the animted element and preciese which animation do you want to use by data-animationattribute. It is also possible to add some delay to the animation (in ms) by data-animation-delay attribute.


Developer Tools

The template was made with NPM package manager and Grunt.js task manager.


The template includes two package.json files:


This file includes necessary grunt tasks to make developemnt process nice and easy. Run npm install task to install them.


This file includes all plugins used in this theme. To install those plugins you need to run npm install as previously but after that you have to run grunt copy and grunt removetasks to move them into right directory



The package includes some grunt tasks to make development process easier:

  • grunt - runs grunt sass tasks after each .scss file change
  • grunt sass - compiles all .scss files
  • grunt cssmin - creates one css with plugins stylesheets
  • grunt uglify - creates one js file with all plugins
  • grunt validation - makes HTML5 validation of each .html file
