Drupal8 W3CSS Theme - Background Color Classes

The ability to set the background color on an HTML page has been around almost since the first Web browsers. However, with CSS you can define the background color, not only for the entire page, but also for individual elements using the background- color property. Unlike the color property, though, background colors are applied only to the element, and are not directly inherited by its children. That said, by the very fact they are within the parent, they will be set against that background. To define the background color of an element: 1.

The idea of a standard way to communicate over the Internet was the principle behind the creation of the World Wide Web: You should be able to transmit information to any computer anywhere in the world and display it in the way the author intended. In the beginning, only one form of HTML existed, and everyone on the Web used it. This situation didn’t present any real problem because almost everyone used Mosaic, the first popular graphics-based browser, and Mosaic was the standard. That, as they say, was then. Along came Netscape Navigator and the first HTML extensions were born.

Drupal8 W3CSS Theme - Effect Classes

Most HTML tags have browser inherited styles associated with them. These default styles are actually defined by the Web browser developer. Because the browser developer has added them, you need to remember that they are there and will affect your design. For example, the tag will italicize text on most browsers. No cosmic constant dictates that emphasized text is italicized; it’s just that the guys and gals programming the browser software decided to do it that way. The good news is that you can use CSS to override the browser styles.

Drupal8 W3CSS Theme - Display Classes

Elements can be classified according to the way they’re displayed—inline or block. By default, every tag has a display style that defines how it will fit with the surrounding tags. You can use the display property to define whether an element includes line breaks above and below (block), is included with other elements without hard line breaks (inline), is treated as part of a list (list), or is displayed at all (none).  To set an element’s display type:
1. Start your declaration by typing the display property name in the CSS declaration block, followed by a colon (:) display:

Drupal8 W3CSS Theme - Table Classes

Setting the Table layout Different browsers use different methods to calculate how a particular table should be displayed. Two primary table-layout. Fixed method bases its layout on the width of the table and the width of columns in the first row. This method is generally faster than automatic.  Automatic uses the table column width along with the amount of content in the table data cell to calculate the table data cell width. This will generally render more slowly than the fixed method, but it also produces more accurate results for widths throughout the table.

Choose an organization scheme You should choose a consistent organization pattern and stick to it. I’m not going to tell you how to organize your style sheets—that depends on what works for you—but here are a few ideas to consider: Organize by selector type. Start with HTML selectors, then IDs, and then classes. Organize based on page structure. Group rules based on their parent tags. This works even better with HTML5 because page structure is stronger. The downside occurs when the same rules need to be applied at different places in the page.

Drupal8 W3CSS Theme - Padding Classes

At first glance, padding seems to have an effect identical to margins: It adds space around the element’s content. The difference is that padding sets the space between the border of the element and its content rather than between the element and the other elements in the window.
