You will be able to configure the color, size, link and link’s target of each button and even add a defaut button for many posts. 
To use it, just take a look on the plugin’s configuration page which contains all the informations and settings for the default button. 
Add the button by using <code>[button color= size= link= target=]text that will be shown as button's value[/button]</code>
Attributes that can be used: 
* color: There is 7 different colors: pink, magenta, green, red, orange, blue and yellow 
* size: There is 4 different sizes: small, medium, large and super 
* link: The link of the button. Example: Your site’s URL http://mysite.com 
* target: The link’s targeted window, can be: blank, new, parent, self or top 
Exemple: <code>[button color=blue size=super link=http://twitter.com/tunilame]Follow me![/button]</code>
Simply add <code>[button]</code> in you posts when you want to use the defaut settings.

CSS3 Buttons

Add coloured CSS3 buttons on your posts using simply a shortcode.

Chris Reynolds

This plugin does one thing: it creates a simple (but nice-looking) CSS3 progress bar that you can style with your own CSS and use wherever you want with a simple shortcode. Now with support for custom colors and gradients.
To add a progress bar to a post or a page, simply use this shortcode:
<pre><code>[wppb progress=50]
</code></pre>
where “50” in the example above is a progress bar that is 50% complete.  Simple, lightweight, cross-browser compatible (degrades nicely for browsers that don\’t support CSS3).
For more examples and full descriptions of all the available options, click on the <a href="https://wordpress.org/extend/plugins/progress-bar/other_notes/" rel="ugc">options tab</a>.
For demos of each of the options, go here: https://progressbar.jazzsequence.com
<h3>Options</h3>
This page describes all the available parameters for the shortcode. These can be used in any combination. The only required parameter is progress. All parameters are case-sensitive (e.g. “progress” will work but “Progress” will not).
<h4>progress (required)</h4>
This determines how full the progress bar will be. Progress can be in 2 forms, either a number (0-100), in which case it will be interpreted as a percentage, or as a fraction (e.g. 25/100). Since 1.1, you can also use dollar signs (e.g. $63/$180), for example to create a fundraising progress bar. If using dollar signs, you only need to add a dollar sign to one or the other of the two values (e.g. 63/$180 or $63/180) — the plugin will output either option the same ($63/$180). Your progress can go over, too (e.g. 150/100 or 123%), but your mileage may vary for the display. It’s not recommended to use this with the fullwidth option, for example, because your progress will spill outside of your main body container.
Examples
<pre><code>[wppb progress=50] A progress bar that is 50% complete

[wppb progress="50/100"] A progress bar that is 50/100 complete

[wppb progress="$45/$50"] A dollar value progress bar that is $45/$50 complete

[wppb progress=110] A progress bar that has gone over 100%

[wppb progress=150/100] A progress bar that has exceeded its goal

[wppb progress=$125/100] A fundraising-style progress bar that has exceeded the goal
</code></pre>
<h4>option</h4>
This adds one of several supported options to the progress bar. For those that know CSS, new “options” can be added simply by adding new styles to your style.css. See the <a href="https://wordpress.org/support/plugin/progress-bar/faq/" rel="ugc">Frequently Asked Questions</a> page for more information on creating new CSS classes. Options can be combined by wrapping them in quotes in the shortcode. The progress bar will naturally have an inner shadow applied to it. The <code>flat</code> option was added to remove the shadow and display a “flat” color, best when used in conjunction with the <code>color</code> parameter.
Supported values: candystripe, animated-candystripe, red, orange, green, yellow, flat
Examples
<pre><code>[wppb progress=50 option=red] Displays a red progress bar

[wppb progress=50 option="animated-candystripe green"] Displays a green progress bar with an animated candystripe

[wppb progress=50 option="candystripe orange"] Displays an orange progress bar with a static candystripe

[wppb progress=50 option=candystripe] Displays a default progress bar (blue) with a static candystripe

[wppb progress=50 option=flat color=red] Displays a red progress bar with no inner shadow or gradient

[wppb progress=50 option="flat candystripe" color=gray] Displays a gray progress bar with no inner shadow or gradient and a static candystripe
</code></pre>
<h4>location</h4>
Displays the percentage, text or fraction either inside or outside the progress bar. 
Note: It is not recommended to use <code>location=after</code> if you are displaying a progress bar that exceeds its goal.
Supported values: inside, after
Examples
<pre><code>[wppb progress=50 option=red location=after] Displays a red progress bar with the progress displayed to the right of the progress bar.

[wppb progress=50 option="red candystripe" location=inside] Displays a red progress bar with a static candystripe and the progress displayed inside the progress bar.

[wppb progress=85 location=after text="foo"] Displays a progress bar with the text "foo" displayed after the progress bar.
</code></pre>
<h4>text</h4>
Displays arbitrary text instead of the progress bar. Can be used with the location parameter to define whether the text appears inside or outside the progress bar (default is inside). Must be used inside double quotes. HTML code is stripped from the final output.
Supported values: any plain text string
Examples
<pre><code>[wppb progress=75 text="My awesome text"] Displays "My awesome text" inside a 75% progress bar.

[wppb progress=85 location=after text="foo"] Displays "foo" after an 85% progress bar

[wppb progress=85 location=inside text="hello!"] Displays "hello!" inside an 85% progress bar (note, default location for text is inside, so it isn't required to specify "inside").
</code></pre>
<h4>fullwidth</h4>
Makes the progress bar take up 100% of the container. (Good for responsive layouts.) Not recommended for progress bars that exceed their goal. 
Note: As of 2.2.4, <code>fullwidth</code> will only take truthy values. Previously, it would accept any value, e.g. <code>fullwidth=foo</code> would output the same as <code>fullwidth=true</code>. This is no longer the case.
Supported value: true
Examples
<pre><code>[wppb progress=50 fullwidth=true] Displays a full-width (responsive) progress bar

[wppb progress=50 fullwidth=foo] Identical to the above progress bar
</code></pre>
<h4>color</h4>
Defines a color for the progress bar. This is useful for creating new progress bar colors on the fly without having to edit CSS. Cannot be used in conjunction with any of the pre-existing color options (red, yellow, orange or green).
Supported values: any hexadecimal color value, any rgb/rgba color value, any css-supported <a href="http://www.w3schools.com/cssref/css_colornames.asp" rel="nofollow ugc">color name</a>
Examples
<pre><code>[wppb progress=50 color=rgb(123,50,87)]

[wppb progress=55 color=rgba(123,64,99,0.3)]
</code></pre>
Note: Since the background color for the progress bar is dark gray, any opacity applied to the rgba color will make the color darker, since it’s adding to the dark gray background.
<pre><code>[wppb progress=22 color=#ff3257]

[wppb progress=68 color=lightYellow]
</code></pre>
<h4>endcolor</h4>
Defines an end color for a custom gradient when used with color.
Supported values: any hexadecimal color value, any rgb/rgba color value, any css-supported <a href="http://www.w3schools.com/cssref/css_colornames.asp" rel="nofollow ugc">color name</a>
Examples
<pre><code>[wppb progress=72 color=turquoise endcolor=teal]

[wppb progress=83 color=#ff2222 endcolor=#ff9984]

[wppb progress=50 color=rgb(203,96,179) endcolor=rgb(173,18,131)]
</code></pre>
<h4>gradient</h4>
Determines an end-color on the fly for a gradient based on the color parameter. As such, gradient requires color to be present, otherwise the color and gradient will be set to the default color (blue). Cannot be used in conjunction with any of the pre-existing color options (red, yellow, orange or green). When using <code>gradient</code> the color value must be in hexadecimal form.
Supported values: any positive or negative decimal value from 0.0 to 1.0 or -1.0.
Examples
<pre><code>[wppb progress=22 color=#ff0000 gradient=0.2] Displays a red progress bar that gets lighter at the bottom

[wppb progress=22 color=#ff0000 gradient=-0.2] Displays a red progress bar that gets darker at the bottom
</code></pre>
This does not work:
<pre><code>[wppb progress=34 color=rgb(22,18,99) gradient=0.2]
</code></pre>
