Wraparound Banner with CSS - html

I'm currently trying to use this CSS to set up a wraparound banner type deal on a website theme I'm working on:
http://asgeirhoem.no/ex/css-wraparound-ribbon/
I've pretty much copied verbatim what's shown on the mentioned site:
(CSS)
header {
position: relative;
margin: 0 -10px;
text-align: center;
padding: 10px;
background-color: #bb0000;
color: white;
text-shadow: 2px 2px 0 black;
}
header:before,
header:after {
content: '';
border-top: 10px solid #660000;
position: absolute;
bottom: -10px;
}
header:before {
border-left: 10px solid transparent;
}
header:after {
border-right: 10px solid transparent;
}
(HTML)
<body>
<div class="page-container">
<header>
<img src="logo1.png" />
</header>
</div>
</body>
But it's not working as expected. This is what I'm getting when I look at the page in a browser:
As you can see, the "wraparound" sections exist, but are not positioned correctly, and I'm not sure why that is. Any help would be fantastic.

You missed the left and right property:
header:before {
border-left: 10px solid transparent;
left: 0;
}
header:after {
border-right: 10px solid transparent;
right: 0;
}

You can use the below as your starting point and adjust the positions according to your needs.
Make use of psuedo selectors to achieve the same. ( there may be limitations on the styling properties)
.box {
width: 150px;
height: 75px;
background-color: black;
color: #fff;
padding: 20px;
position: relative;
margin: 40px;
float: left;
}
.box.arrow-top {
margin-top: 40px;
}
.box.arrow-top:after {
content: " ";
position: absolute;
right: 30px;
top: -15px;
border-top: none;
border-right: 15px solid transparent;
border-left: 15px solid transparent;
border-bottom: 15px solid black;
}
.box.arrow-right:after {

How do I change an active button's appearance to look like it has an arrow pointing

So I want to create a button that looks like this when it's active (you can see that it has a little arrow pointing to the right)
Currently I have something like that, it stays blue after clicked, text turns white and all that. I used .addClass for that, but I have no idea if I should use it again to glue on a triangle onto my button, there has to be a better way right?
While I'm at it, how can I make the shadow/sidebar?
Please, experienced people, give this beginner some enlightenment
add below css for
.active {
height: 50px;
width: 100px;
background: blue;
height: 50px;
width: 100px;
background: blue;
position: relative;
}
.active:after {
content: "";
border-right: 10px solid transparent;
border-top: 10px solid transparent;
border-bottom: 10px solid transparent;
border-left: 10px solid black;
height: 0;
width: 0;
position: absolute;
right: -20px;
top: 50%;
transform: translateY(-50%);
}
<div class="active"></div>
try
.active {
height: 50px;
width: 200px;
background: #0092ff;
}
.active:after {
content: "";
border-style: solid;
border-width: 10px 0 10px 10px;
border-color: transparent transparent transparent #0092ff;
display: block;
margin-left: 200px;
transform: translateY(75%);
}
.active:hover:after {
content: "";
border-left: 0px solid #0092ff;
transition: border-left 0.2s ease-in;
}
<div class="active"></div>
Please Check following working example.
$(function() {
$('.btn').click(function() {
$(this).closest('ul').find('.active').removeClass('active');
$(this).addClass('active');
});
});
ul {
list-style-type: none;
margin: 0;
padding: 0;
}
li a {
padding: 10px;
background: teal;
position: relative;
display: block;
width: 60px;
cursor: pointer;
}
.active::after {
content: " ";
border-right: 10px solid transparent;
border-top: 10px solid transparent;
border-bottom: 10px solid transparent;
border-left: 10px solid teal;
height: 0;
width: 0;
position: absolute;
right: -20px;
top: 50%;
transform: translateY(-50%);
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
<li><a class="btn active">Home</a></li>
<li><a class="btn">News</a></li>
<li><a class="btn">Contact</a></li>
<li><a class="btn">About</a></li>
</ul>
you need to add position:relative to the selector ul li.
after that, you can use the following code below to add content through the pseudo element after of the active link.
change the size of the borders, as well as positions for top and right to suit your needs.
ul li.active:after {
content: "";
width: 0;
height: 0;
border-top: 20px solid transparent;
border-bottom: 20px solid transparent;
border-left: 20px solid #0092ff;
position:absolute;
top: 15px;
right:-15px;
}

Adding a triangle in css under another element

I have been trying hard without success to add a little triangle under my square to act as a pointer like this:
My code by itself works, but whenever I try to add css to make this triangle nothing will appear. I think it has to do with before-after functions, but I'm not really getting it. Anyone can help me with that?
<div id="slider_outer1">
<div class="slider_segment"><img src="myurl.com" alt="Nature" style="width:100%;"></div>
<div id="slider_marker1"></div>
</div>
<style>
.container {width:400px;}
#slider_outer1 {width: 98%;border: 5px solid #8f89ff; position: relative;display: inline-block; border-radius: 5px;}
.slider_segment {width: 100%; float: left; display: inline;}
#slider_marker1 {
position: absolute;
border: 2px solid #574fff;
height: 30px;
width: 5%;
top: 120px;
left: 57.25%;
text-align: center;
Margin-left: -10%;
padding: 5px 0px;
background: #ffffff;
border-radius: 5px;
}
div#slider_marker1:after {
content: "5";
font-size: 20px;
padding: 5px;
line-height: 30px;
font-family: sans-serif;
}
</style>
edit: code of the triangle
<div class="triangle-down"></div>
<style>
.triangle-down {
width: 0;
height: 0;
border-left: 15px solid transparent;
border-right: 15px solid transparent;
border-top: 20px solid #555;
}
</style>
Generally in CSS triangles are made using borders, not before and after pseudo elements. To create a downward pointing triangle, you would create a top border of n number of pixels, and left and right borders of half that width and also transparent.
Example:
<div id="slider_outer1">
<div class="slider_segment"><img src="myurl.png" alt="Nature" style="width:100%;"></div>
<div id="slider_marker1"><div id='triangle-down'></div></div>
</div>
<style>
.container {width:400px;}
#slider_outer1 {width: 98%;border: 5px solid #8f89ff; position: relative;display: inline-block; border-radius: 5px;}
.slider_segment {width: 100%; float: left; display: inline;}
#slider_marker1 {
position: absolute;
border: 2px solid #574fff;
height: 30px;
width: 5%;
top: 120px;
left: 57.25%;
text-align: center;
Margin-left: -10%;
padding: 5px 0px;
background: #ffffff;
border-radius: 5px;
}
#triangle-down {
position: absolute;
top: 40px;
right: 50%;
transform: translateX(50%);
width: 0;
height: 0;
border-left: 10px solid transparent;
border-right: 10px solid transparent;
border-top: 20px solid blue;
}
div#slider_marker1:after {
content: "5";
font-size: 20px;
padding: 5px;
line-height: 30px;
font-family: sans-serif;
}
</style>
See my codepen here: https://codepen.io/anon/pen/bvXOab
You could add another div for the triangle like
<div id='triangle'></div>
Css For the triangle...
#triangle{
width: 0;
height: 0;
border-left: 40px solid transparent;
border-right: 40px solid transparent;
border-top: 80px solid blue;
}
However I feel that your problem is not that it just isnt appearing its that the positioning is messed up so its 'hidden' behind the sliders
I think I understand what you're trying to make. This should add a triangle above the marker. This solution should allow you to also remove anything related to triangle-down as it only requires the slider_marker1 div
#slider_marker1::before {
content: "";
width: 0;
height: 0;
position: absolute;
top: -6px;
left: 0;
right: 0;
margin: auto;
border-left: 4px solid transparent;
border-right: 4px solid transparent;
border-bottom: 4px solid green;
z-index: 100;
}

How to extend the background of a CSS-arrow to the whole page width?

I am trying to create a downward-pointing arrow (.down) with CSS as a decorative element between the sections of a one-page site.
The problem is that the background-color of the .down-class is not spanning the whole width of the page:
This is my code:
HTML:
... </div>
<!-- About End-->
<div id="seperator"></div>
<div class="down"></div>
<!-- Portfolio -->
<div class="container-portfolio"> ... </div>
CSS:
#seperator {
background: #34495E;
height: 10px;
left: 0; right: 0;
}
.down {
width: 0px;
height: 0px;
border-left: 20px solid transparent;
border-right: 20px solid transparent;
border-top: 20px solid #34495E;
margin: 0 auto;
background: #16A085;
background-size: 100%;
}
I already tried to modify the background-size property of the .down-class, unfortunately without success. I would appreciate your advice on this. Thank you.
Try setting the background on the .down div and giving it 100% width, and then creating the 'arrow' as an :after pseudo-element.
#seperator {
background: #34495E;
height: 10px;
left: 0; right: 0;
}
.down {
width: 100%;
background: #16A085;
}
.down:after {
content: '';
display: block;
margin: 0 auto;
width: 0px;
height: 0px;
border-left: 20px solid transparent;
border-right: 20px solid transparent;
border-top: 20px solid #34495E;
}
Like this:
http://jsbin.com/APIyEbIp/1/edit
You might want to wrap another background class. Like this:
#seperator {
background: #34495E;
height: 10px;
left: 0; right: 0;
}
.down {
width: 0px;
height: 0px;
border-left: 20px solid transparent;
border-right: 20px solid transparent;
border-top: 20px solid #34495E;
margin: 0 auto;
}
.down_bkg {
background: #16A085;
background-size: 100%;
width:100%;
}
And HTML is like this:
<div id="seperator"></div>
<div class="down_bkg">
<div class="down"></div>
</div>
Try updating the down class CSS
width:100% or
min-width: 100%

Interesting CSS shape navigation (chevrons)

I'm building a fairly interestingly shaped navigation for a site at the moment. The shape each menu item needs to be is illustrated below:
The final nav will look like an extended version of this:
I thought it would be an interesting experiment to do these shapes in CSS. The CSS and HTML for one of the arrow shapes is here:
.arrowEndOn {
font-size: 10px; line-height: 0%; width: 0px;
border-top: 11px solid #FFFFFF;
border-bottom: 11px solid #FFFFFF;
border-left: 5px solid transparent;
border-right: 5px solid #FFFFFF;
float: left;
cursor: pointer;
}
.arrowBulkOn {
height: 20px;
background: #FFFFFF;
padding: 2px 5px 0px 0px;
float: left;
color: #000000;
line-height: 14pt;
cursor: pointer;
}
.arrowStartOn {
font-size: 0px; line-height: 0%; width: 0px;
border-top: 11px solid transparent;
border-bottom: 11px solid transparent;
border-left: 5px solid #FFFFFF;
border-right: 0px solid transparent;
float: left;
cursor: pointer;
}
<div id="nav" class="navArrow" style="position: relative;">
<div class="arrowEndOn" id="nav"> </div>
<div class="arrowBulkOn" id="nav">NAV</div>
<div class="arrowStartOn" id="nav"> </div>
</div>
Each nav item has a negative offset applied to it (which I've left out of the demo) as it's rendered to get them all flush with each other.
I'm handling the rollovers and on states with Javascript.
My problem is getting the nav to stretch all the way across the width of the page. At the moment I have to set the nav container to a much larger width to accommodate it all.
I've tried setting overflow to hidden but the last item is dropping down a level rather than carrying on and just having the end cut off.
I've set an example up here - http://jsfiddle.net/spacebeers/S7hzu/1/
The red border has overflow: hidden; and the blue doesn't.]
My question is: How can I get the boxes to all float in a line that fills the width of the containing div without them dropping down a level.
Thanks
Add a negative margin to each arrow:
.navArrow {
float: left;
margin-left: -8px;
}
