60 useful CSS code snippets

1. Vertical alignment

---

If you use CSS, you will be confused: how do I vertically align the elements in the container? Now, using Transform of CSS3, this confusion can be solved elegantly:

<code class="css"><span class="hljs-class">.verticalcenter<span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">position:<span class="hljs-value"> relative;
    <span class="hljs-rule"><span class="hljs-attribute">top:<span class="hljs-value"> <span class="hljs-number">50%;
    <span class="hljs-rule"><span class="hljs-attribute">-webkit-transform:<span class="hljs-value"> <span class="hljs-function">translateY(-<span class="hljs-number">50%);
    <span class="hljs-rule"><span class="hljs-attribute">-o-transform:<span class="hljs-value"> <span class="hljs-function">translateY(-<span class="hljs-number">50%);
    <span class="hljs-rule"><span class="hljs-attribute">transform:<span class="hljs-value"> <span class="hljs-function">translateY(-<span class="hljs-number">50%);
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

Use this technique to vertically align everything from single lines of text to paragraphs to boxes. At present, browser support for Transform requires attention.
Chrome 4, Opera 10, Safari 3, Firefox 3, and Internet Explorer 9 all support this attribute

2. Stretch an element to the window height

---

In specific scenarios, you may want to stretch an element to the window height. Adjustment of basic elements can only adjust the size of the container. Therefore, to make an element stretch to the window height,
we need to stretch the top-level element: html and body:

<code class="css"><span class="hljs-tag">html, 
<span class="hljs-tag">body <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">height:<span class="hljs-value"> <span class="hljs-number">100%;
}</span></span></span></span></span></span></span></code>

Then apply 100% to any element’s height

<code class="css"><span class="hljs-tag">div <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">height:<span class="hljs-value"> <span class="hljs-number">100%;
}</span></span></span></span></span></span></code>

3. Use different styles based on file format

---

To make it easier to know where a link is going, sometimes you want some links to look different than others. The snippet below adds an icon before a text link, using different icons or images for different resources:

<code class="css"><span class="hljs-tag">a<span class="hljs-attr_selector">[href^="http://"]<span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">padding-right:<span class="hljs-value"> <span class="hljs-number">20px;
    <span class="hljs-rule"><span class="hljs-attribute">background:<span class="hljs-value"> <span class="hljs-function">url(external.gif) no-repeat center right;
}
<span class="hljs-comment">/* emails */
<span class="hljs-tag">a<span class="hljs-attr_selector">[href^="mailto:"]<span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">padding-right:<span class="hljs-value"> <span class="hljs-number">20px;
    <span class="hljs-rule"><span class="hljs-attribute">background:<span class="hljs-value"> <span class="hljs-function">url(email.png) no-repeat center right;
}

<span class="hljs-comment">/* pdfs */
<span class="hljs-tag">a<span class="hljs-attr_selector">[href$=".pdf"]<span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">padding-right:<span class="hljs-value"> <span class="hljs-number">20px;
    <span class="hljs-rule"><span class="hljs-attribute">background:<span class="hljs-value"> <span class="hljs-function">url(pdf.png) no-repeat center right;
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

4. Create cross-browser image grayscale

---

Grayscale sometimes looks simple and elegant, giving a website a deeper tone. In the example we will add grayscale filtering to an SVG image:

<code class="xml"><span class="hljs-tag"><<span class="hljs-title">svg <span class="hljs-attribute">xmlns=<span class="hljs-value">"http://www.w3.org/2000/svg">
    <span class="hljs-tag"><<span class="hljs-title">filter <span class="hljs-attribute">id=<span class="hljs-value">"grayscale">
        <span class="hljs-tag"><<span class="hljs-title">feColorMatrix <span class="hljs-attribute">type=<span class="hljs-value">"matrix" <span class="hljs-attribute">values=<span class="hljs-value">"0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0"/>
    <span class="hljs-tag"></<span class="hljs-title">filter>
<span class="hljs-tag"></<span class="hljs-title">svg></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

In order to be cross-browser, the filter attribute will be used:

<code class="css"><span class="hljs-tag">img <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">filter:<span class="hljs-value"> <span class="hljs-function">url(filters.svg#grayscale); <span class="hljs-comment">/* Firefox 3.5+ */
    <span class="hljs-rule"><span class="hljs-attribute">filter:<span class="hljs-value"> gray; <span class="hljs-comment">/* IE6-9 */
    <span class="hljs-rule"><span class="hljs-attribute">-webkit-filter:<span class="hljs-value"> <span class="hljs-function">grayscale(<span class="hljs-number">1); <span class="hljs-comment">/* Google Chrome, Safari 6+ & Opera 15+ */
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

5. Background gradient animation

---

One of the most tempting features of

CSS is the ability to add animation effects. In addition to gradients, you can add animations to background color, transparency, and element size. Currently, you cannot animate gradients, but the code below may help. It changes the position of the background to make it look animated.

<code class="css"><span class="hljs-tag">button <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">background-image:<span class="hljs-value"> <span class="hljs-function">linear-gradient(<span class="hljs-hexcolor">#5187c4, <span class="hljs-hexcolor">#1c2f45);
    <span class="hljs-rule"><span class="hljs-attribute">background-size:<span class="hljs-value"> auto <span class="hljs-number">200%;
    <span class="hljs-rule"><span class="hljs-attribute">background-position:<span class="hljs-value"> <span class="hljs-number">0 <span class="hljs-number">100%;
    <span class="hljs-rule"><span class="hljs-attribute">transition:<span class="hljs-value"> background-position <span class="hljs-number">0.5s;
}    
<span class="hljs-rule"><span class="hljs-attribute">button:<span class="hljs-value">hover {
    background-position: <span class="hljs-number">0 <span class="hljs-number">0;
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

6. CSS: Table column width is self-adaptive

---

For tables, when it comes to adjusting column widths, it is more painful. Then, here’s a trick you can use: add white-space: nowrap; to the td element to make the text wrap correctly

<code class="css"><span class="hljs-tag">td <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">white-space:<span class="hljs-value"> nowrap;
}</span></span></span></span></span></code>

7. Display box shadow only on one or both sides

---

If you want a box shadow, try this trick to add shadow to either side. To achieve this, first define a box with a specific width and height, and then position the :after pseudo-class correctly. The code to implement bottom shadow is as follows

<code class="css"><span class="hljs-class">.box-shadow <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">background-color:<span class="hljs-value"> <span class="hljs-hexcolor">#FF8020;
    <span class="hljs-rule"><span class="hljs-attribute">width:<span class="hljs-value"> <span class="hljs-number">160px;
    <span class="hljs-rule"><span class="hljs-attribute">height:<span class="hljs-value"> <span class="hljs-number">90px;
    <span class="hljs-rule"><span class="hljs-attribute">margin-top:<span class="hljs-value"> -<span class="hljs-number">45px;
    <span class="hljs-rule"><span class="hljs-attribute">margin-left:<span class="hljs-value"> -<span class="hljs-number">80px;
    <span class="hljs-rule"><span class="hljs-attribute">position:<span class="hljs-value"> absolute;
    <span class="hljs-rule"><span class="hljs-attribute">top:<span class="hljs-value"> <span class="hljs-number">50%;
    <span class="hljs-rule"><span class="hljs-attribute">left:<span class="hljs-value"> <span class="hljs-number">50%;
}
<span class="hljs-rule"><span class="hljs-attribute">.box-shadow:<span class="hljs-value">after {
    content: <span class="hljs-string">"";
    <span class="hljs-rule"><span class="hljs-attribute">width:<span class="hljs-value"> <span class="hljs-number">150px;
    <span class="hljs-rule"><span class="hljs-attribute">height:<span class="hljs-value"> <span class="hljs-number">1px;
    <span class="hljs-rule"><span class="hljs-attribute">margin-top:<span class="hljs-value"> <span class="hljs-number">88px;
    <span class="hljs-rule"><span class="hljs-attribute">margin-left:<span class="hljs-value"> -<span class="hljs-number">75px;
    <span class="hljs-rule"><span class="hljs-attribute">display:<span class="hljs-value"> block;
    <span class="hljs-rule"><span class="hljs-attribute">position:<span class="hljs-value"> absolute;
    <span class="hljs-rule"><span class="hljs-attribute">left:<span class="hljs-value"> <span class="hljs-number">50%;
    <span class="hljs-rule"><span class="hljs-attribute">z-index:<span class="hljs-value"> -<span class="hljs-number">1;
    <span class="hljs-rule"><span class="hljs-attribute">-webkit-box-shadow:<span class="hljs-value"> <span class="hljs-number">0px <span class="hljs-number">0px <span class="hljs-number">8px <span class="hljs-number">2px <span class="hljs-hexcolor">#000000;
       <span class="hljs-rule"><span class="hljs-attribute">-moz-box-shadow:<span class="hljs-value"> <span class="hljs-number">0px <span class="hljs-number">0px <span class="hljs-number">8px <span class="hljs-number">2px <span class="hljs-hexcolor">#000000;
            <span class="hljs-rule"><span class="hljs-attribute">box-shadow:<span class="hljs-value"> <span class="hljs-number">0px <span class="hljs-number">0px <span class="hljs-number">8px <span class="hljs-number">2px <span class="hljs-hexcolor">#000000;
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

8. Wrap long text

---

If you encounter a text that is longer than its own container, this trick will be useful for you. In this example, by default, the text will fill horizontally regardless of the width of the container.

Simple CSScode to adjust the text in the container:

<code class="css"><span class="hljs-tag">pre <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">white-space:<span class="hljs-value"> pre-line;
    <span class="hljs-rule"><span class="hljs-attribute">word-wrap:<span class="hljs-value"> break-word;
}</span></span></span></span></span></span></span></span></code>

The effect looks like this:

9、制造模糊文本

---

想要让文本模糊？可以使用color透明和text-shadow实现

<code class="css"><span class="hljs-class">.blurry-text <span class="hljs-rules">{
   <span class="hljs-rule"><span class="hljs-attribute">color:<span class="hljs-value"> transparent;
   <span class="hljs-rule"><span class="hljs-attribute">text-shadow:<span class="hljs-value"> <span class="hljs-number">0 <span class="hljs-number">0 <span class="hljs-number">5px <span class="hljs-function">rgba(<span class="hljs-number">0,<span class="hljs-number">0,<span class="hljs-number">0,<span class="hljs-number">0.5);
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>
