The height of block elements (such as div elements) is normally determined by their content.CSS, although quite useful for styling, had limited capabilities for page layout.There were many obstacles to accomplishing this: Another common requirement is that, when a page does not contain enough content to fill the screen, the footer should drop to the bottom of the browser window instead of leaving blank space underneath.ĬSS Layout with floated columns and cleared footer, without holy grail features A common requirement is that the sidebars have a fixed width, with the center column adjusting in size to fill the window (fluid or liquid layout). These columns commonly require separate backgrounds, with borders between them, and should appear to be the same height no matter which column has the tallest content. Many web pages require a layout with multiple (often three) columns, with the main page content in one column (often the center), and supplementary content such as menus and advertisements in the other columns (sidebars). In particular, the CSS Flexible Box Layout and CSS Grid Layout modules have both provided full solutions. More recent web standards have provided much more complete and robust solutions for implementing this layout. These methods were imperfect, inconvenient, and considered by some to be abuse of the web standards and their intent. Common workarounds included changes in page structure, the addition of graphics, scripting, and the creative use of CSS. As the underlying technologies did not provide a proper solution, web designers found various ways to work around the limitations. The limitations of CSS and HTML, the desirability of semantically meaningful pages that rank well in search engines, and the deficiencies of various browsers combined historically to create a situation in which there was no way to create this type of layout that would be considered totally correct. Because of this, finding an optimal implementation was likened to searching for the elusive Holy Grail. It is commonly desired and implemented, but for many years, the various ways in which it could be implemented with available technologies all had drawbacks. The holy grail is a web page layout which has multiple equal-height columns that are defined with style sheets.
