How can you create two triangles next to an image? - html

Question

How can you create two triangles next to an image?
As you can see in the jsfiddle, the triangles are not tounching the image. I want them to touch the image and the blue bar above.
I tried this post: How can I have an image float next to a centered div? didn't work.
.content {
width: 960px;
margin: 0 auto;
}
ul.producten {
margin-top: 4%;
list-style-type: none;
}
ul.producten li {
width: 315px;
}
ul.producten li img {
display: inline-block;
width: 295px;
}
.producten_top {
width: 315px;
height: 40px;
background: #3bcdff;
}
.producten_top h1 {
font-size: 30px;
color: #fff;
text-align: center;
padding: 5px 0;
}
.arrow_left {
display: inline-block;
width: 0;
height: 0;
border-left: 5px solid transparent;
border-right: 5px solid transparent;
border-top: 5px solid #1c1c1d;
transform: rotate(225deg);
float: left;
}
.arrow_right {
display: inline-block;
width: 0;
height: 0;
border-left: 5px solid transparent;
border-right: 5px solid transparent;
border-bottom: 5px solid #1c1c1d;
transform: rotate(315deg);
float: right;
}
<div class="content">
<ul class="producten">
<li>
<div class="producten_top"><h1>Test</h1></div>
<div class="arrow_left"></div>

Answer 1

Use position: absolute instead of display: inline-block and give 8px border for triangles instead of 5px and set display: block and margin: auto for make img center. of course you need to set position: relative; for parent (ul.producten li).
.content {
width: 960px;
margin: auto;
}
ul.producten {
margin-top: 4%;
list-style-type: none;
}
ul.producten li {
width: 315px;
position: relative;
}
ul.producten li img {
display: block;
width: 295px;
margin: auto;
}
.producten_top {
width: 315px;
height: 40px;
background: #3bcdff;
}
.producten_top h1 {
font-size: 30px;
color: #fff;
text-align: center;
padding: 5px 0;
}
.arrow_left {
width: 0;
height: 0;
border-left: 8px solid transparent;
border-right: 8px solid transparent;
border-top: 8px solid #1c1c1d;
transform: rotate(225deg);
position: absolute;
left: 0;
top: 39px;
}
.arrow_right {
width: 0;
height: 0;
border-left: 8px solid transparent;
border-right: 8px solid transparent;
border-bottom: 8px solid #1c1c1d;
transform: rotate(315deg);
position: absolute;
right: 0;
top: 39px;
}
<div class="content">
<ul class="producten">
<li>
<div class="producten_top"><h1>Test</h1></div>
<div class="arrow_left"></div>
<div class="arrow_right"></div>
<img src="http://assets.worldwildlife.org/photos/144/images/hero_small/Giant_Panda_Hero_image_(c)_Michel_Gunther_WWF_Canon.jpg?1345515244" alt="Plafond lampen">
</li>
</ul>
</div>

Answer 2

This technique makes a square div with a linear gradient alpha background that resembles a triangle. As a bonus, by adjusting the distance between alpha=1 and alpha=0 (the percentages) in the gradients you can change the anti-aliasing of the diagonal line (the left arrow has more anti-aliasing in this example).
.content {
width: 960px;
margin: 0 auto;
}
ul.producten {
margin-top: 4%;
list-style-type: none;
}
ul.producten li {
width: 315px;
position: relative;
}
ul.producten li img {
display: block;
width: 295px;
margin: auto;
}
.producten_top {
width: 315px;
height: 40px;
background: #3bcdff;
}
.producten_top h1 {
font-size: 30px;
color: #fff;
text-align: center;
padding: 5px 0;
}
.arrow_left {
width: 10px;
height: 10px;
background: linear-gradient(225deg, rgba(28,28,29,1) 44%,rgba(28,28,29,0) 56%);
position: absolute;
left: 0;
top: 40px;
}
.arrow_right {
width: 10px;
height: 10px;
background: linear-gradient(135deg, rgba(28,28,29,1) 48%,rgba(28,28,29,0) 50%);
position: absolute;
right: 0;
top: 40px;
}
<div class="content">
<ul class="producten">
<li>
<div class="producten_top"><h1>Test</h1></div>
<div class="arrow_left"></div>
<div class="arrow_right"></div>
<img src="http://assets.worldwildlife.org/photos/144/images/hero_small/Giant_Panda_Hero_image_(c)_Michel_Gunther_WWF_Canon.jpg?1345515244" alt="Plafond lampen">
</li>
</ul>
</div>

Answer 3

I have modified your css. The changes I made are:
Set the same width for the blue header and image
Set position fixed for image and right arrow
Set the arrows degrees values in negative
