A) HTML Structure
Petro - Industrial HTML Template. It is built using bootstrap 3.3.2 framework, works totally responsive, easy to customise, well commented codes and seo friendly
This template made with Bootstrap, using HTML5, CSS3, JS and jQuery.
<!-- Load page --> <div class="animationload"> ... </div> <!-- HEADER --> <div class="header"> ... </div> <!-- BANNER --> <div id="slides" class="section banner"> ... </div> <!-- ABOUT FEATURE --> <div class="section feature overlap"> ... </div> <!-- ABOUT COMPANY --> <div class="section why section-border bglight"> ... </div> <!-- PROJECTS --> <div class="section project"> ... </div> <!-- SERVICES --> <div class="section services"> ... </div> <!-- TESTIMONIALS --> <div class="section testimony bglight"> ... </div> <!-- CTA --> <div class="section cta"> ... </div> <!-- BLOG --> <div class="section blog"> ... </div> <!-- CLIENT --> <div class="section stat-client"> ... </div> <!-- INFO BOX --> <div class="section info overlap-bottom"> ... </div> <!-- FOOTER SECTION --> <div class="footer"> ... </div>

If you would like to edit the color, font, or style of any elements in one of these columns, you would do the following:
.section-heading { color: #someColor; }
If you find that your new style is not overriding, it is most likely because of a specificity problem. Scroll down in your CSS file and make sure that there isn't a similar style that has more weight.
.services .section-heading { color: #someColor; }
So, to ensure that your new styles are applied, make sure that they carry enough "weight" and that there isn't a style lower in the CSS file that is being applied after yours.
B) CSS Files and Structure
On the CSS side, we load different css files depending on the page that loads.
How to change a title/font from css
We recommend using the FireBug add on in Firefox for a fast identification of the css properties that you might want to change. Lets say for example that we want to change the color and add a link to the h1 represented in the picture below.
Open the style.css file form the root folder and search h3 until you find the color property in the file. Its on line 260 and it looks line this:
h1,
h2,
.banner-page .title-page,
h3,
h4,
h5,
.section-subheading,
h6 {
clear: both;
font-weight: 700;
margin: 0;
text-rendering: optimizeLegibility; }
Change the color with the one you want and hit save. Note that you've changed the color to all the headings (h3, h4 and h5). If you want to change only the h3 color, you have to separate the h3 and give it another color. The css should look like this.
h1,
h2,
.banner-page .title-page,
h4,
h5,
.section-subheading,
h6{
clear: both;
font-weight: 700;
margin: 0;
text-rendering: optimizeLegibility; }
h3{
color: #12aaeb;
}
Now, lets say we wanted h1 to poin to http://google.com. At this point the h1 looks like this:<h1>Shortcodes: Typography & paragraph styles</h1>
To make it point to a specific URL the h1 must look like this:
<h1><a href="http://www.google.com">Shortcodes: Typography & paragraph styles</a></h1>
You can make changes to the css to any elements. You just need to know the name of the element or div either by using FireBug or by opening the HTML and then search for that element in the css. Piece of cake!
Social Icons
To add a link to your social icon paste the necessary URL into the <a href=> tag. See the example below:
<a href="#"><i class="fa fa-facebook"></i></a>
Box Info
You can customize the box info icon by changing <div class="fa fa-envelope-o"></div> values as well as their styles. Check below screenshot.
<div class="box-icon-4">
<div class="icon">
<div class="fa fa-envelope-o"></div>
</div>
<div class="body-content">
<div class="heading">Email Support</div>
info@petro.com
</div>
</div>
<div class="box-image-4">
<a href="project-detail.html" title="Industrial Complex">
<div class="media">
<img src="images/project-img-1.jpg" alt="" class="img-responsive">
</div>
<div class="body">
<div class="content">
<h4 class="title">INDUSTRIAL COMPLEX
<span class="category">Commodoenim
</div>
</div>
</a>
</div>
Box Image
You can customize the image by changing <img src="" /> values as well as their styles. Check below screenshot.
<div class="box-image-1">
<div class="image">
<a href="services-detail.html" title="House Insurance">
<img src="images/500x350.jpg" alt="" class="img-responsive">
</a>
</div>
<div class="description">
<h3 class="blok-title">House <br/>Insurance</h3>
<a href="contact-quote.html" title="GET A QUOTE" class="btn btn-secondary">GET A QUOTE</a>
</div>
</div>
Video Popup
You can customize the necessary URL into the <a href=> tag. See the example below:
<a class="popup-youtube" href="https://www.youtube.com/watch?v=JGYuCRYFxew"> <span class="fa fa-play fa-3x playvid"></span> </a>
C) JavaScript
This template imports different js files for the different sliders, lightboxes and interactive tabs from the homeplage and the rest of the pages. All the js is built around JQuery. What follows are some examples where jQuery was used:
Maps Google

<div class="maps-wraper"> <div id="cd-zoom-in"></div> <div id="cd-zoom-out"></div> <div id="maps" class="maps" data-lat="-7.452278" data-lng="112.708992" data-marker="images/cd-icon-location.png"> </div> </div>
you can change coordinate google map by edited the atribute data-lat for latitute and data-lng for langitude. And Icon Marker by edited the attribute data-marker.
Contact Form

Open the file in "php/form-process.php" line 27
$EmailTo = "emailaddress@test.com"
edited 'emailaddress@test.com' with your email
D) Search Engine Optimization
