I loaded in multiple images on my website from the internet. Is it possible to give all those images an hexagon shape in a responsive grid?

<div>
    <img src="link" class="Image">
</div>

<div>
    <img src="link" class="Image">
</div>
...

I found multiple ways to do this but you needed to fill in the image src in the CSS code. This isnt possible for me cause the website loads in random images from the internet with jQuery so I can't use background images.

I tried this: http://jsfiddle.net/8f5m5wv0/

Here is the demo and the repositery for the responsive grid of hexagons. The code here isn't maintained. It was moved to github and improved so comments, issue reporting and contributions should be made there.

Responsive grid of hexagons

This technique uses :

  • the <img> tag
  • an unordered list : each hexagon is contained in a <li> tag and an <a> tag
  • transform rotate and skew to make the hexagon shapes
  • overflow:hidden;
  • nth-child() to space the hexagons in a regular pattern

And more to create the hexagon grid with the <img> tag.

Hexagon grid features :

  • The grid is responsive as it relies on percent widths. The hexagons maintain their aspect ratio with the padding-bottom technique and the images resize to fit the hexagon shape.
  • A hover effect over the hexagons : a text slides in with a transparent overlay over the image.
  • Each hexagon maintains its boundaries : the hover effect (or click event) for each hexagon only triggered inside the actual shape.

The following snippet isn't the latest version of the grid. The GitHub repo is maintained and up to date. Issues and contributions can be made there.

Changing the number of hexagons per row

The grid adapts the number of hexagons per row according to the viewport width from 5 on screens wider than 1200px to 2 on screens narrower than 600px.

If you don't need the media queries but just want to change the number of hexagons per row, you can keep the CSS from the corresponding media query and remove the unneeded ones.

For more customization, see sizing and spacing of hexagons.


Demos

For a list of all the demos, see this codepen collection: Responsive grids of hexagons with different numbers of hexagons per row, centering options and more...

Here is the original codepen demo with the .pusher element to make an irregular grid of hexagons. The .pusher element is used to make the "holes" in the grid with empty hexagons.

You can make responsive grid of squares with vertically and horizontally centered content only with CSS. I will explain how in a step by step process but first here are 2 demos of what you can achieve:

  • Grid of square images
  • Grid of squares with content

Responsive 3x3 square grid Responsive square images in a 3x3 grid

Now let's see how to make these fancy responsive squares!



1. Making the responsive squares :

The trick for keeping elements square (or whatever other aspect ratio) is to use percent padding-bottom.
Side note: you can use top padding too or top/bottom margin but the background of the element won't display.

As top padding is calculated according to the width of the parent element (See MDN for reference), the height of the element will change according to its width. You can now Keep its aspect ratio according to its width.
At this point you can code:

HTML :

<div></div>

CSS :

div {
    width: 30%;
    padding-bottom: 30%; /* = width for a square aspect ratio */
}

Here is a simple layout example of 3*3 squares grid using the code above.

With this technique, you can make any other aspect ratio, here is a table giving the values of bottom padding according to the aspect ratio and a 30% width.

 Aspect ratio  |  padding-bottom  |  for 30% width
------------------------------------------------
    1:1        |  = width         |    30%
    1:2        |  width x 2       |    60%
    2:1        |  width x 0.5     |    15%
    4:3        |  width x 0.75    |    22.5%
    16:9       |  width x 0.5625  |    16.875%

2. Adding content inside the squares :

As you can't add content directly inside the squares (it would expand their height and squares wouldn't be squares anymore) you need to create child elements (for this example I am using divs) inside them with position: absolute; and put the content inside them. This will take the content out of the flow and keep the size of the square.

Don't forget to add position:relative; on the parent divs so the absolute children are positioned/sized relatively to their parent.

Let's add some content to our 3x3 grid of squares :

HTML :

<div class="square">
    <div class="content">
        .. CONTENT HERE ..
    </div>
</div>
... and so on 9 times for 9 squares ...

CSS :

.square {
    float: left;
    position: relative;
    width: 30%;
    padding-bottom: 30%; /* = width for a 1:1 aspect ratio */
    margin: 1.66%;
    overflow: hidden;
}

.content {
    position: absolute;
    height: 80%; /* = 100% - 2*10% padding */
    width: 90%; /* = 100% - 2*5% padding */
    padding: 10% 5%;
}

RESULT <-- with some formatting to make it pretty!


3. Centering the content :

Horizontally :

This is pretty easy, you just need to add text-align:center to .content.
RESULT

Vertical alignment :

This becomes serious! The trick is to use

display: table;
/* and */
display: table-cell;
vertical-align: middle;

but we can't use display:table; on .square or .content divs because it conflicts with position:absolute; so we need to create two children inside .content divs. Our code will be updated as follow :

HTML :

<div class="square">
    <div class="content">
        <div class="table">
            <div class="table-cell">
                ... CONTENT HERE ...
            </div>
        </div>
    </div>
</div>
... and so on 9 times for 9 squares ...

CSS :

.square {
    float:left;
    position: relative;
    width: 30%;
    padding-bottom : 30%; /* = width for a 1:1 aspect ratio */
    margin:1.66%;
    overflow:hidden;
}

.content {
    position:absolute;
    height:80%; /* = 100% - 2*10% padding */
    width:90%; /* = 100% - 2*5% padding */
    padding: 10% 5%;
}

.table{
    display:table;
    height:100%;
    width:100%;
}

.table-cell{
    display:table-cell;
    vertical-align:middle;
    height:100%;
    width:100%;
}

We have now finished and we can take a look at the result here :

Oh boy, yeah, you're gonna have trouble with this one. It drives me nuts that ListViews and GridViews can't be expanded to wrap their children, because we all know that they have more beneficial features in addition to their scrolling and the recycling of their children.

Nonetheless, you can hack around this or create your own layout to suit your needs without too much difficulty. Off the top of my head, I can think of two possibilities:

In my own app I have embedded a ListView within a ScrollView. I have done this by explicitly telling the ListView to be exactly as high as its contents. I do it by changing the layout parameters right inside the ListView.onMeasure() method like so:

public class ExpandableListView extends ListView {

    boolean expanded = false;

    public ExpandableListView(Context context, AttributeSet attrs, int defaultStyle) {
        super(context, attrs, defaultStyle);
    }

    public boolean isExpanded() {
        return expanded;
    }

    public void setExpanded(boolean expanded) {
        this.expanded = expanded;
    }

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // HACK!  TAKE THAT ANDROID!
        if (isExpanded()) {         
            // Calculate entire height by providing a very large height hint.
            // View.MEASURED_SIZE_MASK represents the largest height possible.
            int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK,
                        MeasureSpec.AT_MOST);
            super.onMeasure(widthMeasureSpec, expandSpec);

            LayoutParams params = getLayoutParams();
            params.height = getMeasuredHeight();
        } else {
            super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        }
    }
}

This works because when you give the ListView a mode of AT_MOST, it creates and measures all of its children for you, right inside the onMeasure method (I discovered this by browsing through the source code). Hopefully GridView behaves the same, but if it doesn't, you can still measure all the contents of the GridView yourself. But it would be easier if you could trick the GridView into doing it for you.

Now, you must keep in mind that this solution would completely disable the view recycling that makes GridView so efficient, and all those ImageViews will be in memory even if they're not visible. Same goes with my next solution.

The other possibility is to ditch the GridView and create your own layout. You could extend either AbsoluteLayout or RelativeLayout. For example, if you extend RelativeLayout, you could place each image LEFT_OF the previous one, keeping track of the width of each image until you run out of room on that row, and then start the next row by placing the first image of the new row BELOW the tallest image of the last row. To get the images horizontally centered or in equally-spaced columns you'll have to go through even more pain. Maybe AbsoluteLayout is better. Either way, kind of a pain.

Good luck.

Solution:

http://jsfiddle.net/WTWrB/

The DIV structure:

We use overflow:hidden in .x2 for spill off background colors in .x3 of child elements.

Notice the content starts inside of .x3

<div class="x0">
    <div class="x1">
        <div class="x2">
            <div class="x3">
                <!-- BEG Content -->
                <div class="x4">
                    dude
                </div>
                <div class="x6">
                    <div class="x7">
                        dude
                    </div>
                    <div class="x8">
                        dude
                    </div>
                </div>                
                <div class="x5">
                    dude
                </div>
                <!-- END Content -->
            </div>
        </div>
        <div class="x2"></div>
        <div class="x2"></div>
        <div class="x2"></div>
    </div>
</div>

The CSS:

@media (max-width: 320px)
{
    .x2 {padding: 50%;}
}

@media (min-width: 321px) and (max-width: 800px)
{
    .x2 {padding: 25%;}
}

@media (min-width: 801px)
{
    .x1 {width:800px}
    .x2 {padding: 12.5%;}
}
.x0 {
    float:left;
    width:100%;
}
.x1 {
    margin:0px auto;
}
.x2 {
    overflow:hidden;
    display:block;
    float:left;
    width:auto;
    height:auto;
    position: relative;
    border-radius:50%;
    -moz-border-radius:50%;
    -webkit-border-radius:50%;
    -khtml-border-radius: 50%;
    background:#eee;
}
.x3 {
    position: absolute;
    width: 100%;
    left: 0;
    top:0;
    font-size: 100%;
    float:left;
    height:100%;
    background-color:red;
}
/* BEG Content */
.x3 div{float:left;}
.x4,.x5,.x6 {
    width:100%;
}
.x7,.x8 {
    width:50%;
    float:left;
    height:100%;
}
.x4,.x5,.x7,.x8 {
    text-align:center;
}
.x4 {
    background-color:blue;
    height:20%;
}
.x5 {
    background-color:yellow;
    height:20%;
}
.x6 {
    height:60%;
}
.x7 {
    background-color:green;
}
.x8 {
    background-color:orange;
}
/* END Content */

Responsive CSS Circles

Viewport Units

If you use the same viewport unit (either vw or vh) then you should get a responsive circle.

A viewport unit of 100 would be 100% of either the width or height. Therefore it is very similar to using a percentage.

div {
  width: 10vw;
  height: 10vw;
  border-radius: 50%;
  background: blue;
}
<div></div>
