To include stylesheet rules, use the element or style attribute or even external stylesheet using .The element can be used to include an external style sheet file in your HTML document.An external style sheet is a separate text file with .css extension. You define all the Style rules within this text file and then you can include this file in any HTML document using element.Here is the syntax of including external CSS file: The following are the attributes of a element:AttributeValueDescriptionTypetext/cssSpecifies the style sheet language as a content-type (MIME type). This attribute is required.HrefURLSpecifies ... Read More
Associate styles with your HTML document using methods inline CSS and External CSS.You can use style attribute of any HTML element to define inline style rules. These rules will be applied to that element only. Here is the generic syntax:The following is the attribute:AttributeValueDescriptionstylestyle rulesThe value of style attribute is a combination of style declarations separated by a semicolon (;).Let us see an example: This is inline CSS
The text-transform property is used to capitalize text or convert text to uppercase or lowercase letters.ExamplePossible values are none, capitalize, uppercase, lowercase. This will be capitalized This will be in uppercase This will be in lowercase
You can put your CSS rules into an HTML document using the element. This tag is placed inside ... tags. Rules defined using this syntax will be applied to all the elements available in the document.ExampleFollowing is an example of embedded CSS using the element: body { background-color: linen; } h1 { color: maroon; margin-left: 40px; } This is a heading This is a paragraph.
You may need to define multiple style rules for a single element. You can define these rules to combine multiple properties and corresponding values into a single block as defined in the following example: h1 { color: #36C; font-weight: normal; letter-spacing: .4em; margin-bottom: 1em; text-transform: lowercase; }Here all the property and value pairs are separated by a semicolon (;). You can keep them in a single line or multiple lines. For better readability, we keep them on separate lines.
You can define style rules based on the id attribute of the elements. All the elements having that id will be formatted according to the defined rule. #black { color: #000000; }This rule renders the content in black for every element with id attribute set to black in our document. You can make it a bit more particular. For example:h1#black { color: #000000; }This rule renders the content in black for only elements with id attribute set to black.The true power of id selectors is when they are used as the foundation for descendant selectors, For example:#black h2 ...

You can define style rules based on the class attribute of the elements. All the elements having that class will be formatted according to the defined rule..black { color: #808000; }This rule renders the content in black for every element with class attribute set to black in our document. You can make it a bit more particular. For example:h1.black { color: #808000; }This rule renders the content in black for only elements with class attribute set to black.You can apply more than one class selectors to given element. Consider the following example: This para will be ... Read More
Given the task is to show the working of deque::crbegin() in C++.Deque is a double ended queue that gives insertion and deletion at each end i.e. front and back with high performance, in contrast to vector that gives high performance insertion at the end i.e. back only.Also, it provides random access to components too. Though one can insert part in between alternative components in dequeue with insert(), however its performance won't be sensible rather like a vector.What is deque::crbegin()?Deque::crbegin(), where crbegin is the constant reverse begin, implies it constantly reverse the begin or in other words it returns the constant_reverse_iterator.What ...

Except for control characters, (+ ? . * ^ $ ( ) [ ] { } | \), all characters match themselves. You can escape a control character by preceding it with a backslash.Following table lists the regular expression syntax that is available in Python −Sr.No.Pattern & Description1^Matches beginning of line.2$Matches end of line.3.Matches any single character except newline. Using m option allows it to match newline as well.4[...]Matches any single character in brackets.5[^...]Matches any single character not in brackets6re*Matches 0 or more occurrences of preceding expression.7re+Matches 1 or more occurrence of preceding expression.8re?Matches 0 or 1 occurrence of preceding ...

Regular expression literals may include an optional modifier to control various aspects of matching. The modifiers are specified as an optional flag. You can provide multiple modifiers using exclusive OR (|), as shown previously and may be represented by one of these −Sr.No.Modifier & Description1re.IPerforms case-insensitive matching.2re.LInterprets words according to the current locale. This interpretation affects the alphabetic group (\w and \W), as well as word boundary behavior(\b and \B).3re.MMakes $ match the end of a line (not just the end of the string) and makes ^ match the start of any line (not just the start of the string).4re.SMakes ...
