why use role attribute in html5 [duplicate] - html

This question already has answers here:
What is XHTML role attribute? What do you use it for?
(3 answers)
Closed 8 years ago.
I have created a web page using html5.
I used source code from bootstrap.
For example: role="main", role ="navigation", role = "document" etc.
If I remove these attribute from my code, page didn't any change.
So I want to know: what is the purpose of "role" attribute?

It provides support for ARIA (Accessible Rich Internet Applications) which allows to specify even more semantic richness in documents.
You can add role="search" to your search form, role="banner" to your
masthead, and role="contentinfo" to your page footer. There’s a full
list of values in the ARIA specification at
http://www.w3.org/TR/wai-aria/roles#role_definitions.
Basically you don't have to add them, but its better if you do as it provides more context for your page. More discussed at A List Apart.

The new structural elements in HTML5 will be very useful to assistive technology. Instead of creating “skip navigation” links, all we need to do is use the nav element correctly. This will allow screen reader users to skip past navigation without us having to provide an explicit link.
Twitter Bootstrap uses like <nav role="navigation">. So Bootstrap take consider not only normal browser but also take care of screen reader browsers.
Note: By including Role attribute you are making your website more accessible and its good practice to use this Role attribute.

A link on top of an image link

I'm building a landing page and I encounter a problem. I have an image of a project that when is clicked will zoom in a gallery mode and on top of that image it is a link towards the Behance page of the project. But what ever I do when I click the project link is opening still the image gallery. This is my code:

I am trying to have this section in a website I'm creating. As you can see, I am using the Bootstrap grid system to make sure the text is only within a certain box. Problem is the text still fills the entire page so the Bootstrap doesn't seem to work. Maybe I'm not doing something right.
Have you included bootstrap 4 and fontawesome css files with jquery in header?
content is showing in bootstrap grid layout only. see my code below and fiddle and check the versions of bootstrap css and js files

Part of my HTML is not displaying in Chrome

The top third of my page, including a graphic and headline, shows up just fine in Firefox and Explorer, but does not appear in Chrome when accessed from my server. It does appear in Chrome when viewing the page as a file.
The graphic is defined in the CSS file as:
/** adbox **/
#adbox {
background: #020a13 url(../images/bg-adbox.jpg) no-repeat center top;
font-family: Georgia, "Times New Roman", Times, serif;

The Google Chrome extension AdBlock is blocking that element for me, because its ID is adbox. Check if you have that extension enabled, as well.
In general, try avoiding the word "ad" when naming HTML elements.
From the start, I can see a major flaw in the code- you named an element adbox. Most ad-blocking extensions work this way- they scan for ads, and that element will be perceived as an ad, simply because of it's name.
To quote CapitalQ,
In general, try avoiding the word "ad" when naming HTML elements.
Check if you have an ad-blocking extension turned on, and if so, try the site without that extension. Also, rename that element ASAP!

No background in IE and Firefox

I've recently designed a website and have realised that some of the background of the content, when you scroll down is transparent and so the fixed div that is beneath the content displays on IE and Firefox. Please see my website for a live view of the problem. The HTML is below. Please see below an image of my problem as you can see the text "Get In Touch" is being displayed. I want the background of the content to be above this. Please find attached the fiddle.

You have an empty P tag inside your post-container that is causing this gap. Remove it and it will fix everything accross all browsers. Also, once the empty tag is removed, you could give the last P element (with the "My favourite book" text) a padding-bottom of 45px to push the container down correctly.

This looks like a nesting issue. Your sidebar is within the same block element as your #content. Thusly floats will not work properly. FireFox and other browsers are most likely auto-correcting it, but IE8 is limited and does not give guess work to assist.
I would correct the issue by placing the #sidebar_wrap_right and placing it at the same level as #content. Then be sure to add a width to both in CSS and float the 2 divs left adding margin/padding as needed.
I also have never seen the tag below that is rendering, it is possible you have some invalid HTML and CSS as well.
<css3-container style="z-index: auto; position: absolute; direction: ltr; top: 5500px; left: 28px;">
