Up triangle, adjusting the y position in CSS - html

Hey I have a triangle in CSS created like so:
.triangleup {
width: 0;
height: 0;
border-style: solid;
border-width: 0 7.5px 10px 7.5px;
border-color: transparent transparent #58BE23 transparent;
display: inline-block;
}
<h1>Here is a triangle<i class="triangleup"></i></h1>
I would like to change the y position of the triangle and move it up so the top of the triangle aligns with the top of the text. How would I go about doing this?

Try This:
.triangleup {
vertical-align: top;<----------Added
//More code.........
}
.triangleup {
width: 0;
height: 0;
border-style: solid;
border-width: 0 7.5px 10px 7.5px;
border-color: transparent transparent #58BE23 transparent;
display: inline-block;
vertical-align: top;
}
<h1>Here is a triangle<i class="triangleup"></i></h1>

There are 2 ways you could do this, i.e. align triangle at top so that it level-up with remaining texts,
1st - By changing the position of .triangleup to position:relative and using top as negative value,
.triangleup {
width: 0;
height: 0;
border-style: solid;
border-width: 0 7.5px 10px 7.5px;
border-color: transparent transparent #58BE23 transparent;
display: inline-block;
position:relative; /*Add this*/
top:-22px; /*Add this*/
}
<h1>Here is a triangle<i class="triangleup"></i></h1>
2nd - By changing the position of .triangleup to position:absolute and top:0, here you even need to change position of h1 to relative.
position:absolute - The element is removed from the normal document
flow; no space is created for the element in the page layout. Instead,
it is positioned relative to its closest positioned ancestor if any;
otherwise, it is placed relative to the initial containing block.
h1{
position:relative;
}
.triangleup {
width: 0;
height: 0;
border-style: solid;
border-width: 0 7.5px 10px 7.5px;
border-color: transparent transparent #58BE23 transparent;
display: inline-block;
position:absolute;
top:0;
}
<h1>Here is a triangle<i class="triangleup"></i></h1>

You could try putting some margin on the bottom of the triangle
.triangleup {
margin-bottom: 10px;
}

margin-left:50px;
margin-top:50px;
This is used to set the position of the top left corner point of the triangle.

margin-bottom:10px;
This code in css will fix the issue

.triangleup {
position:absolute;
width: 0;
height: 0;
border-style: solid;
border-width: 0 7.5px 10px 7.5px;
border-color: transparent transparent #58BE23 transparent;
display: inline-block;
top:0px;
}
h1{
background-color:blue;
position:relative;
}
<h1>Here is a triangle<i class="triangleup"></i></h1>
Make your h1 element position:relative and traingleup class position:absolute.
Now it works.
Hope it help.

Other answers here give you some possibilities that will work with the specific example you've given, but may require adjusting the numbers a bit depending on your real-life font size and font family.
A more abstract solution that will give you roughly the correct alignment no matter the font is to use the CSS property meant specifically for this purpose: vertical-align: text-top.
Simply setting that property will automatically align the bottom of your triangle to the top of your text.
If you want to align the top of the triangle, you can then do what others have suggested and add relative positioning to the vertical alignment. Since your triangle is 10 pixels tall, you can use top: 10px (in conjunction with position: relative) to push the triangle down so its top will then align with the top of the text.
Final styles would look like this:
.triangleup {
width: 0;
height: 0;
border-style: solid;
border-width: 0 7.5px 10px 7.5px;
border-color: transparent transparent #58BE23 transparent;
display: inline-block;
vertical-align: text-top;
position: relative;
top: 10px;
}
Whether that gets the triangle to sit close enough to where you want it to or not will be the deciding factor on if you go this route or one of the routes others have presented. This method is, I think, more flexible at the expense of being slightly less precise.

You can align it with applying position. So the code will be:
.triangleup {
border-color: transparent transparent #58be23;
border-style: solid;
border-width: 0 7.5px 10px;
display: inline-block;
height: 0;
position: relative;
top: -3px;
width: 0;
}

matching triangle to div element

I'm trying to add a triangle before a div in navigationTable using css, but I cant correctly match it with a div element.
Here's code
tmp tmp tmp
How solve this problem?
edit:
second problem: how to make edges of triangle smooth?
Absolute positioned element will be relative to the next parent element with relative (or absolute) positioning.
.elem{
color: dodgerblue;
font-weight: bold;
padding: 10px 20px;
position:relative; //YOU NEED THIS LINE
}
.elem:hover:before {
display: inline-block;
content: "";
top:0; //YOU NEED THIS LINE
width: 0;
height: 0;
border-style: solid;
border-width: 10px 15px 10px 0;
border-color: transparent red transparent transparent;
left: -15px;
position: absolute;
border-top: 20px solid transparent;
border-bottom: 20px solid transparent;
}
So what did you need. You need(ed) .elem to be relative, so that .elem:before could be positioned relative to that. You've also "forgot" to set top property (to 0).

Center text over a responsive triangle?

I have to center text on top of (or inside of) a triangle, which is bleeding off the right side. Ideally I'd like it to be responsive, but all I could get to work was fixed pixel widths/margins on both the triangle and the content. Like so:
View my Demo
.triangle-down:after {
content: "";
border-style: solid;
position: absolute;
right: 0;
top: 0;
margin-left: -450px;
border-width: 550px 450px 0 450px;
border-color: red transparent transparent transparent;
}
You can see what I'm trying to accomplish better if you look at it wider than 960px. (It will just be a red rectangle below 768px.) I suppose I can work with this if there's no other choice because I can make sure the text inside the triangle will always be roughly the same word count.
But is there a better way to accomplish this layout in a responsive design without having to use fixed pixels?
Use this,
Html code :
<div class="up">
<p>some information text goes here<p>
</div>
Css code :
.up {
width: 0px;
height: 0px;
border-style: inset;
border-width: 0 100px 173.2px 100px;
border-color: transparent transparent #007bff transparent;
float: left;
transform:rotate(360deg);
-ms-transform:rotate(360deg);
-moz-transform:rotate(360deg);
-webkit-transform:rotate(360deg);
-o-transform:rotate(360deg);
}
.up p {
text-align: center;
top: 80px;
left: -47px;
position: relative;
width: 93px;
height: 93px;
margin: 0px;
}

CSS3-triangle before div

I'm trying to add a triangle before a div using css, but it ends up under it.
http://jsfiddle.net/lasseedsvik/LwE7u/
HTML
<div id="container">
1234
<div id="toolbar">
Want silly triangle before this div to left
</div>
</div>
CSS
#container {
width: 500px;
}
#toolbar:before
{
width: 44px;
content: '';
height: 0px;
border-style: solid;
border-width: 0 0 44px 44px;
border-color: transparent transparent blue transparent;
}
#toolbar {
float: right;
width: 350px;
height: 44px;
background: blue;
color: #fff;
}
Is there something missing like display: inline or something?
Use CSS Positioning to set the triangle correctly, in the example below, I am using position: relative; on the parent element, and than use position: absolute; for the :before pseudo..and than use left property which is dobule of the elements width
Always you should wrap the absolute positioned elements with a relative positioned containers, else your element will fly out in the wild.
Demo
#container {
width: 500px;
}
#toolbar:before {
position: absolute;
left: -88px; /* Double the element size */
width: 44px;
content: '';
height: 0px;
border-style: solid;
border-width: 0 0 44px 44px;
border-color: transparent transparent blue transparent;
}
#toolbar {
float: right;
width: 350px;
height: 44px;
background: blue;
color: #fff;
position: relative;
}
Note: Generally when you are creating triangles using CSS, it's a
common practice to set the elements height and width to 0 so if
you want, just tweak them up.
Try putting your div#toolbar in position:relative and positionning your pseudo-element in an absolute manner. Then adjust position and margins to position it correctly.

You were missing some crucial points in your triangle on the right. First of all, by default a :before element is display: inline, so to create the effect you were seeking you needed display: block instead.
Second, the right: 120px was moving it 120 pixels away from the right side of its original position. That is, it was being pushed to the left, out of view. Instead, you needed a negative right position (move to the right) of 100% (the width of the speech bubble). That way, it'd end up to the right of it.
Third, not sure what shape you were going for but it was almost everything but a triangle ;).
I went for this instead:
#talkbubble:before
{
content:" ";
display: block;
position: relative;
right: -100%;
width: 0;
height: 0;
border-left: 0 solid transparent;
border-right: 20px solid transparent;
border-bottom: 35px solid #FFCC05;
}
​The first part is for the positioning, the second part is creating the actual triangle (see http://css-tricks.com/snippets/css/css-triangle/).
In the jsfiddle I made the triangle blue so you can see exactly where it is. Change the border-right width to make the angle bigger. http://jsfiddle.net/USezL/31/

How to make a pure css triangle which has a white center

I want to create an upward and downward facing arrow with css like the following: http://apps.eky.hk/css-triangle-generator/
However, instead of a solid color, I want to set it up so the inside is white and there is just a border around the triangle. (So the triangle would be multi-colored, one color on the inside and a different colored border).
Is this possible, and if so, how can it be done?
To create triangles with only CSS we use a zero width/height element with borders:
.arrow-up {
width : 0;
height : 0;
border-left : 50px solid transparent;
border-right : 50px solid transparent;
border-bottom : 50px solid black;
}
Since we are using borders to create the arrow, we can't just give it a border, but we can overlay one arrow on top of a slightly larger arrow to make the appearance of a border:
HTML --
<div class="top"></div>
<div class="bottom"></div>​
CSS --
.top {
position : absolute;
top : 6px;
left : 10px;
width : 0;
height : 0;
z-index : 100;
border-left : 50px solid transparent;
border-right : 50px solid transparent;
border-bottom : 50px solid black;
}
.bottom {
position : absolute;
width : 0;
height : 0;
z-index : 99;
border-left : 60px solid transparent;
border-right : 60px solid transparent;
border-bottom : 60px solid red;
}​
Here is a demo: http://jsfiddle.net/jasper/qnmpb/1/
Update
You can then put both of the triangle DIV elements inside a container and move that container however you want:
HTML --
<div id="container">
<div class="top"></div>
<div class="bottom"></div>
</div>
CSS --​
#container {
position : relative;
top : 25px;
left : 25px;
}

EDIT (2014):
I just came back to this answer and noticed that separate HTML elements are not necessary to create your double-triangle. You can use pseudo-elements, :before and :after. I.e. replace the .top selector with something like .my-element-that-needs-a-triangle:before and the .bottom selector with something like .my-element-that-needs-a-triangle:after.
I think you could get a good idea of what to do by checking out this tutorial on pure css thought bubbles. It's doing what you're looking for.
http://www.sitepoint.com/pure-css3-speech-bubbles/
Depending on how you're using it, you can make a triangle, with a border and even box shadow, without the triangle border hack, using CSS transform: rotate(). See my answer here: https://stackoverflow.com/a/8867645/918414
If you want to create a triangle with borders (or box shadow look-alike) in pure CSS, you should use pseudo-elements :before and :after.
In my example, I added display:inline-block; to the element .arrow-dropdown to be able to create some kind of dropdown menu with a drop shadow. It is followed by .arrow-only which is a a basic triangle with a red border.

margin: 10px;
background: #1670c4;

}
.arrow-dropdown {
display: inline-block;

margin: 1px 0 0 8px;
