My floated elements are being pulled too far to the left - html

Question

I'm new to CSS, and I've looked for help in the previous forums on this issue. I think I'm doing everything right but my floated elements are being yanked to the left.
Here is my code:
div {
display: block;
}
.grid {
width: 660px;
position: relative;
float: left;
padding-bottom: 10px;
clear: left;
}
.home {
text-align: center;
float: left;
width: 33.3333333%;
position: relative;
padding: 25px;
}
.third {
display: inline-block;
position: relative;
float: left;
height: 150px;
width: 150px;
border-radius: 25px;
}
.third img {
float: left;
position: relative;
}
And my html:
<div class="grid">
<article class="home">
<article class="third">
<img src="" /></article>
</article>
<article class="home">
<article class="third">
<img src="" /></article>
</article>
<article class="home">
<article class="third">
<img src="" /></article>
</article>
</div>
Help please!

I can't comment yet…
Your original code on fiddle
The problem come from padding in .home class.
I have disabled padding:25px; here in .home class, because padding is added to width in CSS:

Now it's not "pulled too far on the left".
What you can do instead, is to add margin:25px; to .third class, like this:

EDIT: A CLEAN REVISITED VERSION:
The HTML code:
<div class="grid">
<article class="home">
<div class="third">
<img src="http://lorempicsum.com/nemo/350/200/1" />
</div>
</article>
<article class="home">
<div class="third">
<img src="http://lorempicsum.com/futurama/350/200/6" />
</div>
</article>
<article class="home">
<div class="third">
<img src="http://lorempicsum.com/up/350/200/6" />
</div>
</article>
</div>
The CSS code:
.grid {
width: 660px;
position: relative;
float: left;
padding-bottom: 10px;
clear: left;
}
.home {
text-align: center;
float: left;
width: 33.3333333%;
}
.third {
display:table-cell;
height: 150px;
width: 150px;
padding: 25px;
border-radius:25px;
vertical-align:middle;
background-color:#eee; //added just for test display
}
.third img {
border:none;
width: 100%;
height: auto;
}
The result here on fiddle.
Images are adaptative, centered vertically and horizontally.
The .third class have a light grey background color just for testing and displaying the curved borders and the centered images inside it.
I have also replaced in html code, the second <article> tag by a <div> tag, because it is redundant.

Please use the updated code I think it will work.
div {
display: block;
}
.grid {
width: 660px;
position: relative;
float: left;
padding-bottom: 10px;
clear: left;
}
.home {
text-align: center;
float: left;
width: 33.3333333%;
position: relative;
padding: 25px;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
.third {
display:block;
border-radius: 25px;
}
.third img {
width:100%;
height:auto;
}

Here's a possible correction of your code to you :
See this fiddle
I've changed a little the HTML structure like this :
<section class="home">
<article class="third">
<img src="http://lorempicsum.com/futurama/350/200/1" />
</article>
<article class="third">
<img src="http://lorempicsum.com/futurama/350/200/1" />
</article>
<article class="third">
<img src="http://lorempicsum.com/futurama/350/200/1" />
</article>
</section>
It's better for semantic to have section around article and not article around article.
I've simplify the CSS code like this :
section.home {
width: 660px;
position: relative;
float: left;
padding-bottom: 10px;
clear: left;
}
article.third {
text-align: center;
float: left;
width: 150px;
position: relative;
padding: 25px;
overflow: hidden;
}
.third img {
border-radius: 25px;
width: 100%;
position: relative;
}
If you use fluid width for container, then use fluid width for padding/margin of article.
In that case, i use fixed width of the container and for padding values.
