Typografia16.4.2013/ FCV Sisältö TypographyHeadingsAll HTML headings, <h1> through <h6> are available.h1. Heading 1h2. Heading 2h3. Heading 3h4. Heading 4h5. Heading 5h6. Heading 6Built with LessThe typographic scale is based on two LESS variables in variables.less: @baseFontSize and @baseLineHeight. The first is the base font-size used throughout and the second is the base line-height. We use those variables and some simple math to create the margins, paddings, and line-heights of all our type and more. Customize them and Bootstrap adapts.Body copyBootstrap’s global default font-size is 14px, with a line-height of 1.7em. This is applied to the <body> and all paragraphs. In addition, <p> (paragraphs) receive a bottom margin of half their line-height (9px by default).Nullam quis risus eget urna mollis ornare vel eu leo.

Search<form class="form-search"> <input type="text" class="input-medium search-query"> <button type="submit" class="btn">Search</button> </form>Inline formAdd .form-inline for left-aligned labels and inline-block controls for a compact layout.

For example, .input-large will increase the padding and font-size of an input.Uneditable inputsPresent data in a form that’s not editable without using actual form markup. Some value here<span class="input-xlarge uneditable-input">Some value here</span>Form control states Provide feedback to users or visitors with basic feedback states on form controls and labels.Input focusWe remove the default outline styles on some form controls and apply a box-shadow in its place for :focus. <input class="input-xlarge" id="focusedInput" type="text" value="This is focused...">Disabled inputsAdd the disabled attribute on an input to prevent user input and trigger a slightly different look. <input class="input-xlarge" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>Validation statesBootstrap includes validation styles for error, warning, and success messages.
