<p>The <strong class=css>margin-top</strong> property sets the top margin of an element by specifying a <a href="../units.html#length">length</a> or a <a href="../units.html#percentage">percentage</a>. Percentage values refer to the parent element's width. Negative margins are permitted.</p>
<p>For example, the following rule would eliminate the top margin of a document:</p>
<pre><code class=css>BODY { margin-top: 0 }</code></pre>
<p>Note that adjoining vertical margins are collapsed to use the maximum of the margin values.</p>

<p>Example:</p>

<p>The <strong class=css>margin</strong> property sets the margins of an element by specifying between one and four values, where each value is a <a href="../units.html#length">length</a>, a <a href="../units.html#percentage">percentage</a>, or <strong class=css>auto</strong>. Percentage values refer to the parent element's width. Negative margins are permitted.</p>
<p>If four values are given, they apply to top, right, bottom, and left margin, respectively. If one value is given, it applies to all sides. If two or three values are given, the missing values are taken from the opposite side.</p>
<p>Examples of margin declarations include:</p>
<pre><code class=css>BODY { margin: 5em } /* all margins 5em */
P { margin: 2em 4em } /* top and bottom margins 2em,
left and right margins 4em */
DIV { margin: 1em 2em 3em 4em } /* top margin 1em,
right margin 2em,
bottom margin 3em,
left margin 4em */</code></pre>
<p>Note that adjoining vertical margins are collapsed to use the maximum of the margin values. Horizontal margins are not collapsed.</p>
<p>Using the <strong class=css>margin</strong> property allows one to set all margins; alternatively, the properties <strong class=css><a href="#margin-top">margin-top</a></strong>, <strong class=css><a href="#margin-bottom">margin-bottom</a></strong>, <strong class=css><a href="#margin-left">margin-left</a></strong>, and <strong class=css><a href="#margin-right">margin-right</a></strong> may be used.</p>

<p>The <strong class=css>padding-top</strong> property describes how much space to put between the <a href="#border-top">top border</a> and the content of the selector. The value is either a <a href="../units.html#length">length</a> or a <a href="../units.html#percentage">percentage</a>. Percentage values refer to the parent element's width.

The initial value for the <strong class=css>height</strong> property is <strong class=css>auto</strong>, which results in the element's intrinsic height (<i>i.e.</i>, the height of the element itself, for example the height of an image). Negative lengths are not allowed.</p>
<p>As with the <strong class=css><a href="#width">width</a></strong> property, <strong class=css>height</strong> can be used to scale an image:</p>
<pre><code class=css>IMG.foo { width: 40px; height: 40px }</code></pre>
<p>In most cases, authors are advised to scale the image in an image editing program, since browsers will not likely scale images with high quality, and since scaling down causes the user to download an unnecessarily large file. However, scaling through the <strong class=css>width</strong> and <strong class=css>height</strong> properties is a useful option for user-defined style sheets in order to overcome vision problems.</p>

<p>The <strong class=css>float</strong> property allows authors to wrap text around an element. This is identical in purpose to <a href="../../wilbur/index.html">HTML 3.2</a>'s <strong class=html>ALIGN=left</strong> and <strong class=html>ALIGN=right</strong> for the <strong class=html>IMG</strong> element, but CSS1 allows all elements to "float," not just the <a href="../../html40/special/img.html">images</a> and <a href="../../html40/tables/table.html">tables</a> that HTML 3.2 allows.</p>

<p>The <strong class=css>clear</strong> property specifies if an element allows floating elements to its sides. A value of <strong class=css>left</strong> moves the element below any floating element on its left; <strong class=css>right</strong> acts similarly for floating elements on the right. Other values are <strong class=css>none</strong>, which is the initial value, and <strong class=css>both</strong>, which moves the element below floating elements on both of its sides. This property is similar in function to <a href="../../wilbur/index.html">HTML 3.2</a>'s <strong class=html><BR CLEAR=left|right|all|none></strong>, but it can be applied to all elements.</p>
