The notable exception is the behavior of margins in Flex Layout. Border The border of a box can be styled with several border properties. The borders can either be individually styled with border-top , border-right , border-bottom and border-left , or the shorthand property border can be used to style all four borders of the box in the same way. To style the borders, the border-color , border-style and border-width properties can be used. For each of them, also top, right, bottom and left variants are available to style each border separately.
The property border-radius property can be used for styling rounded corners. The border-clip property splits the borders into parts along the border edge - the first part is visible, the second one is invisible, the third part is visible, etc. Padding The property padding defines the padding inside the box model. Each padding's size can be set individually with the properties padding-top , padding-bottom , padding-left and padding-right , or you can use the shorthand property padding to specify all four paddings together.
The syntax of the shorthand property is: padding : top right bottom left If there are only: three values: then the left padding is set equal to the right padding; two values: then the left padding is set equal to the right padding, and the bottom padding is set equal to the top padding; one value: then all paddings are made equal. Background The background of an element can be styled with the background-color and the background-image properties, or with the shorthand property background.
See also Background Images. Various standard properties are available to position the background, to clip it or to determine whether, and how it should be repeated. Prince extends control on the background with the prince-background-image-resolution property, used to control image size in print see Image Size.
Most elements are displayed as either block or inline elements. The default display value can be changed with the display property.
A block element always starts on a new line and takes up all the available width. An inline element, on the other hand, does not start on a new line, and only takes up as much space as necessary. A hybrid type, namely the inline-block element, is like inline elements, but it can have a width and a height - which can be very useful when you want to create a grid of CSS boxes that fills all the width and wraps nicely.
The inside of an inline-block element is formatted like a block box. Care needs to be taken with inline-block elements, because Prince cannot split them over several pages. The value run-in displays a block element as if it were an inline element at the beginning of the following block element.
With the value list-item, the element is effectively transformed into a list item - for more on lists, please see the chapter Lists. The value flex enables Flex Layout , while inline-flex makes an element behave like an inline element and lays out its content according to the flex layout model.
Several values refer to Tables , making elements behave as if they were table elements.
Dom Casmurro by Machado de Assis
However, the value inline-table has no direct equivalent in HTML - it behaves like a table HTML element, but as an inline element, rather than a block element. Inside the table box is a block context. The special value none, which removes the content from the document, is very useful when hiding certain elements in the printed layout. Transformations Prince supports CSS transformations of Level 1, with some limitations: it recognizes transform and transform-origin, but does not recognize transform-box.
Furthermore, Prince does not allow perspective transforms. The transform property can be used to rotate, translate, scale or skew an element. The transform property currently does not affect SVG elements - they need to use their own transform attribute instead see SVG Transformations. The transform property function rotate rotates the element clockwise from its current position.
Negative values rotate conter-clockwise. The functions translatex and translatey move the element along one of those axis only.
The function translate3d is supported if the Z third coordinate is zero, thus making it equivalent to the 2D translate. The function scale affects the size of the element - note that this also alters other properties of an element, such as its font-size , padding , height and width.
The functions scalex and scaley transform the element in one dimension only. The functions skewx and skewy tilt an element to the left or right. There is no shorthand form. The origin for the transformations, i. Below I detail the values returned for nodeType and nodeName for the node objects discussed in this book.
It makes sense to simply memorize these numeric code's for the more common nodes given that we are only dealing with 5 numeric codes. Below we check to see if the anchor element has a node number of 1. If it does than we can conclude that its an Element node because Node. Notes The values returned by the nodeName property vary according to the node type. Have a look at the DOM 4 specification provided for the details.

The string is the same string that is returned from the tagName property of an Element object. The createAttribute method is depricated and should not be used for creating attribute nodes. Instead developers typically use getAttribute , setAttribute , and removeAttribute methods.
I will discus this in more detail in the Element node chapter.
The createDocumentFragment will be discussed in the chapter covering this method. You should be aware that a createComment method is available for creating comment nodes.
Its not discussed in this book but is very much available to a developer who finds its usage valuable. It too accepts an optional options array, but the only option available is compress the default is true.
We can add text, lines, images, rectangles, etc. All drawing will be recorded into that object and we can add this object to all or selected pages though there are limitations.
Next we fetch the actual width and height of the page to calculate the coordinates of the footer we intend to add.
Also, we need to provide a font object while we add text contents. The line method draws a line from point X1,Y1 to X2,X2.
Notice that the color value we provided is not an actual RGB value.
To get a better approximation, you can divide it by Chinese scripts. The line method draws a line from point X1,Y1 to X2,X2.
According to Atala, nixtamalization is one of the oldest Meso-American and South American cooking techniques and was used by Incas and Mayas in the preparation of several vegetables. All drawing will be recorded into that object and we can add this object to all or selected pages though there are limitations.
Layout Layout is the way in which text and pictures are set out on a page. All drawing will be recorded into that object and we can add this object to all or selected pages though there are limitations. It takes the same values as text-align.
